SUMMARY:A polyhedral view of refined q-t Catalan numbers (Max Hlavacek\, Pomona College)
DESCRIPTION:Title: A polyhedral view of refined q-t Catalan numbers \nSpeaker: Max Hlavacek Assistant Professor of Mathematics and Statistics department\, Pomona College\, Claremont \nAbstract: Many problems in algebraic combinatorics have geometric objects lurking in the background\, and bringing these objects forward can shed some light on the original problem.  We begin with an introduction to polyhedral cones and their connection to multivariable generating functions.  Then\, we pivot and introduce Catalan-Minggatu numbers and some of their generalizations\, including refined q-t Catalan numbers\, first introduced by Xin and Zhang in 2022. Finally\, we take a look at the polyhedral cones underlying these objects and see how these geometric objects can give us insight into open problems about refined q-t Catalan numbers. \nBio: Max Hlavacek is a Visiting Assistant Professor in the mathematics and statistics department at Pomona College.  Previously\, they were a graduate student at UC Berkeley and an undergraduate student at Harvey Mudd College.  They are interested in problems in enumerative geometric combinatorics\, particularly concerning discrete volumes of polytopes.  They love thinking about math with others\, and especially enjoy learning about the interplay between polyhedral objects such as cones and polytopes and their friends’ and collaborators’ mathematical interests. \nThe talk is based on joint work with Matthias Beck\, Mitsuki Hanada\, John Lentfer\, Andrés R. Vindas-Meléndez\, and Katie Waddle. \n

SUMMARY:An Invitation to Enumerative Geometric Combinatorics (Andrés R. Vindas Meléndez\, Harvey Mudd College)
DESCRIPTION:Speaker: Andrés R. Vindas Meléndez\, Assistant Professor of Mathematics\, Harvey Mudd College\, Claremont CA \nTitle: An Invitation to Enumerative Geometric Combinatorics \nAbstract: Enumerative geometric combinatorics is an area of mathematics concerned with counting properties of geometric objects described by a finite set of building blocks. Lattice polytopes are geometric objects that can be formed by taking the convex hull of finitely many integral points. In this talk I will present background on polytopes\, lattice-point enumeration\, and share some results on special families and properties of polytopes that can be further studied. Throughout the talk I will present questions and open problems. \nBio:  Andrés R. Vindas Meléndez\,  is an Assistant Professor of Mathematics at Harvey Mudd College. His research interests are in algebraic\, enumerative\, and geometric combinatorics. His scholarly interests have also expanded to include mathematical & computational approaches and applications of data science and mathematics for social justice. He has also been a research member for the SLMath Fall 2023 program on Algorithms\, Fairness\, & Equity and a research scholar at the Institute for Computational and Experimental Research Mathematics [ICERM] for the program on Data Science & Social Justice: Networks\, Policy\, & Education during the Summers of 2022 and 2023. \nProf. Andrés strives to create community in order to build mathematics users’ confidence in spite of society’s negative messages and stigma about mathematics. He also aims to build meaningful and empowering experiences with mathematics\, while also challenging others to think about the power structures that are present in and outside mathematical spaces. \n

SUMMARY:CCMS Colloquium: Inaugurual Barbara Beechler Lecture
DESCRIPTION:CCMS Colloquium invites you to the final talk of the 2023-2024 academic year and the inaugural Barbara Beechler Lecture by Professor Judy Grabiner\, Flora Sanborn Pitzer Professor of Mathematics Emerita. \nTitle: It’s All for the Best: Optimization in the History of Science \nAbstract: Many problems\, from optics to economics\, can be solved mathematically by finding the highest\, the quickest\, the shortest – the best of something. This has been true from antiquity to the present. Why did we start looking for such explanations\, and how did we conclude that we could productively do so? Scientific examples will include problems from ancient optics\, and more modern questions in optics and classical mechanics\, drawing on ideas from Newton’s and Leibniz’s calculus and from the Euler-Lagrange calculus of variations. A surprising role will also be played by philosophical and theological ideas\, including those of Leibniz\, Maupertuis\, MacLaurin\, and Adam Smith. \nSpeaker Bio: Judith V. Grabiner received her B.S. in mathematics with honors from the University of Chicago\, and her PhD at Harvard in the History of Science\, with advisors I Bernard Cohen and Dirk Struik. For fourteen years she was a Professor of History at California State University\, Dominguez Hills\, and then for thirty years was Professor of Mathematics at Pitzer College. She has also taught at various times at Harvard\, UC Santa Barbara\, Cal State LA\, UCLA\, Pomona College\, and the University of Leeds in England. \nHer publications have received three Carl B. Allendoerfer Awards for the best article in Mathematics Magazine\, and she is the only four-time winner of the MAA’s Lester Ford award for best article in the American Mathematical Monthly. In 2003 she received the MAA’s Haimo award for teaching mathematics\, principally for her courses in mathematics for liberal arts students. In 2014 her book A Historian Looks Back: The Calculus as Algebra and Selected Writings won the Beckenbach Book Prize from the MAA. She is a Fellow of the American Mathematical Society\, and in 2021 won the Albert Leon Whiteman prize from the AMS for what they called “her outstanding contributions to the history of mathematics\, in particular her works on Cauchy\, Lagrange\, and MacLaurin; her widely-recognized gift for expository writing; and a distinguished career of teaching\, lecturing\, and numerous publications promoting a better understanding of mathematics and the significant roles it plays in culture generally.” \n

SUMMARY:Structural Ramsey Theory and Logic (Lynn Scow\, CSUSB)
DESCRIPTION:Title: Structural Ramsey Theory and Logic \nSpeaker: Lynn Scow\, Professor of Mathematics\, California State University\, San Bernardino \nAbstract: The connection between Ramsey theory and logic goes back to Frank P. Ramsey’s 1929 paper in which he announced his famous Ramsey theorem for finite sequences.  This theorem states that for any partition of all sequences of length $k$ from $\mathbb{N}$ into finitely many pieces\, there is an infinite subset $X \subset \mathbb{N}$ such that all sequences of length $k$ from $X$ lie in one piece of this partition.  In the intervening years\, Ramsey theory has been used to study problems in logic\, and vice versa.  In this talk\, I will survey some results from the last few decades\, as well as highlight some results obtained with my coauthor Dana Bartošová at University of Florida. \n\n\n\n\n\nLynn Scow studied mathematics and philosophy at UC Berkeley as an undergraduate and continued on to earn her Ph.D. in mathematics from UC Berkeley.  She then held a postdoctoral position at University of Illinois Chicago followed by a visiting position at Vassar College\, and is currently faculty at California State University\, San Bernardino.  Her research area is primarily in foundations and mathematical logic\, including applications of structural Ramsey theory to model theory and vice versa.  She treasures mathematics for the conversations\, the shared understandings\, and the joy.

SUMMARY:A Survey of Diophantine Equations (Edray Goins\, Pomona College)
DESCRIPTION:Title: A Survey of Diophantine Equations \nSpeaker: ​Edray Herber Goins\, Professor of Mathematics and Statistics\, Pomona College \nAbstract: There are many beautiful identities involving positive integers. For example\, Pythagoras knew $3^2 + 4^2 = 5^2$ while Plato knew $3^3 + 4^3 + 5^3 = 6^3$. Euler discovered $59^4 + 158^4 = 133^4 + 134^4$\, and even a famous story involving G.~H.~Hardy and Srinivasa Ramanujan involves $1^3 + 12^3 = 9^3 + 10^3$. But how does one find such identities?  Around the third century\, the Greek mathematician Diophantus of Alexandria introduced a systematic study of integer solutions to polynomial equations. In this talk\, we’ll focus on various types of so-called Diophantine Equations\, discussing such topics as Pythagorean Triples\, Pell’s Equations\, Elliptic Curves\, and Fermat’s Last Theorem. \n\n\n\n\nEdray Herber Goins is Professor of Mathematics and Statistics at Pomona College. He has worked as a researcher at both Harvard and the National Security Agency; and has taught at both Caltech and Purdue. Professor Goins has published over 25 journal articles in areas such as applied mathematics\, graph theory\, number theory\, and representation theory; and on topics such as Diophantine equations\, elliptic curves\, and African Americans in mathematics. He has given nearly 300 invited addresses on his research\, acted as a referee for nearly 20 different journals in mathematics\, served on dozens of panels for the National Science Foundation (NSF)\, and been awarded more than $1\,370\,000 in external funding.  Goins currently maintains the website “Mathematicians of the African Diaspora (MAD Pages)”\, and runs a federally-funded Research Experience for Undergraduates (REU) titled Pomona Research in Mathematics Experience (PRiME).

SUMMARY:Teaching Equity-minded Active Mathematics: A model for Instructional Change (Amelia Stone-Johnstone\, CSU Fullerton)
DESCRIPTION:Title: Teaching Equity-minded Active Mathematics: A model for Instructional Change \nSpeaker: ​Amelia Stone-Johnstone\, Department of Mathematics\, California State University\, Fullerton \nAbstract: Active learning has been championed as a mechanism for greater student learning and participation in STEM. However\, recent studies have demonstrated how active learning without an explicit equity focus may harm students from historically marginalized communities in STEM. In this talk\, I will introduce a model for professional development that attends both to equity and active learning. In addition\, I will introduce the Teaching Equity-minded and Active Mathematics (TEAM) Tool\, a tool for pedagogical reflection that was developed by a team of undergraduate students at California State University\, Fullerton. This research-backed tool was constructed as a way to support faculty in creating a learning atmosphere in which students can explore\, discuss\, and learn mathematics in the classroom in a safe\, just\, active\, and equitable manner. \n\n\n\n\n\nAmelia Stone-Johnstone is an Assistant Professor in the Mathematics Department at California State University\, Fullerton. Her research involves the development and assessment of academic support systems in introductory mathematics courses. In addition\, Dr. Stone-Johnstone’s research and service include faculty professional development on equity-minded instruction.

SUMMARY:A Group-Theoretic Ax-Katz Theorem (Pete L. Clark\, University of Georgia)
DESCRIPTION:Title: A Group-Theoretic Ax-Katz Theorem \nSpeaker: Pete L. Clark\, University of Georgia \nAbstract: The Chevalley-Warning Theorem is a result from 1935 asserting that the number of solutions to a low degree polynomial system over a finite field is divisible by the characteristic of the field.  It is an important result — it includes a conjecture of Artin and Dickson from the 1920’s — but it is not difficult to prove: the original proof is about three pages.  In 1964 James Ax gave a completely elementary ten line proof.   In the same paper\, Ax showed that as the number and degrees of the polynomials are held fixed and the number of variables increases\, not only is the size of the solution set divisible by p but by higher and higher powers of p.  The best possible p-adic divisibility here was given in 1971 by Nicholas Katz.  Katz’s proof is at a much higher level: you need specialist knowledge in the right subfields of number theory to understand it.  Simpler proofs were found later\, but none fulfills the fantasy of generalizing Ax’s ten line proof of Chevalley-Warning. \nA 2021 work of Aichinger-Moosbauer develops a fully fledged calculus of finite differences for maps between commutative groups and uses it to give a purely group-theoretic generalization of Chevalley-Warning. Nicholas Triantafillou and I have used and extended this work: up to a few black boxes (where most of the content is indeed hidden) we give a ten line proof of a group-theoretic analogue of Ax-Katz that “qualitatively fulfills my fantasy.”\n\n\n\n\n\nIn (North)west Philadelphia was Pete L. Clark born and raised.  He received undergraduate and masters degrees from the University of Chicago and a PhD from Harvard University.  He has worked in the Mathematics Department at the University of Georgia since 2006\, where he was the Graduate Coordinator from 2016-2019 and where he is now the Principal Honors Advisor.  When time permits he is an avid reader\, and his favorite authors include Ralph Ellison\, Jonathan Franzen\, Kazuo Ishiguro\, Carmen Maria Machado and Lorrie Moore.

SUMMARY:Evolution of an Intriguing Recreational Math Problem (Shawn McMurran\, California State University San Bernardino)
DESCRIPTION:Title: Evolution of an Intriguing Recreational Math Problem \nSpeaker: Shawn McMurran\, California State University San Bernardino \nAbstract: Besides being popular and entertaining\, recreational mathematics problems are often of historical interest. In this presentation we will highlight the origin and evolution of one such simply stated yet deep problem. The problem emerged during the eighteenth century tucked into a primarily standard arithmetic text. Over the next two centuries\, several notable names contributed to a growing collection of extensions\, generalizations\, and solution strategies. In more recent years\, relatives of this versatile problem have remained ubiquitous. It is likely that most audience members are familiar with at least one of its incarnations. During our journey\, opportunities will be provided for the audience to engage with the problem and some of its variations. \n\n\n\n\n\nShawn McMurran is a professor of mathematics at California State University San Bernardino. She earned her PhD in mathematics from UC Riverside with a background in PDEs. Current areas of interest include mathematics education and history of mathematics. She and her colleague Jim Tattersall have enjoyed many years of collaboration on math history projects\, including the subject of this presentation.

SUMMARY:Mirror Symmetry and Zeta Values (Sheel Ganatra\, USC)
DESCRIPTION:Title: Mirror Symmetry and Zeta Values \nSpeaker: Sheel Ganatra\, University of Southern California \nAbstract: Mirror symmetry is a conjectural correspondence\, born out of ideas in string theory\, between two geometries of very different nature. In its earliest mathematical appearance\, mirror symmetry was used to make predictions for certain numerical measurements of one space in terms of utterly different calculations on a mirror space. Mysteriously\, certain famous arithmetic constants\, the Riemann zeta values\, were repeatedly observed to appear in the transformation taking measurements on one side to measurements on the mirror side.  I will survey these ideas and then present joint work with Abouzaid\, Iritani\, and Sheridan explaining a geometric origin for the appearance of these constants in mirror symmetry. \n\n\n\n\n\nSheel Ganatra is an Associate Professor at the University of Southern California. Prior to coming to USC in 2016\, he completed his PhD at MIT with Denis Auroux in 2012 (two years of which were on exchange at UC Berkeley) and spent 4 years as a Szegö Assistant Professor and NSF postdoctoral Fellow at Stanford. His research interests include symplectic geometry and mirror symmetry\, and he is the recipient of an NSF Career Award and a Simons Fellowship.

SUMMARY:Shrinkage Estimation for Causal Inference and Experimental Design (Evan T. R. Rosenman)
DESCRIPTION:Title: Shrinkage Estimation for Causal Inference and Experimental Design \nSpeaker: Evan T. R. Rosenman\, Assistant Professor of Statistics\, Claremont McKenna College \nAbstract: Passive collection of observational data — in settings such as medicine\, insurance\, and e-commerce — is a ubiquitous feature of modern life. For statisticians\, these ever-proliferating datasets are both promising and perilous. Observational data often contain rich information about the causal effects of novel treatments\, such as a new vaccine or drug regimen. Yet\, because assignment to treatment is not randomized within these data\, one can never guarantee that treated and untreated units are comparable. Consequently\, causal effects derived from observational studies often suffer from bias. The applied literature contains myriad examples of treatments that seemed promising in observational data\, only to be overturned by later\, higher-quality studies. \nHow might we make headway\, given these challenges? One approach is to couple observational data with randomized trials. In this talk\, I will consider how to develop estimators to merge causal effect estimates obtained from observational and experimental datasets\, when the two data sources measure the same treatment. I will primarily operate in the Empirical Bayes (EB) framework. EB procedures\, rooted in the work of Charles Stein and the renowned James-Stein estimator\, offer principled\, data-driven methods for reconciling competing estimates of the same quantity. I will discuss two techniques for deriving EB estimators that effectively merge observational and experimental causal estimates. Additionally\, I will explore the potential contribution of these concepts to improving the efficiency of prospective randomized trials. Simple algorithms\, leveraging numerical integrals\, will be highlighted for making more informed recruitment and treatment assignment decisions within the experimental setup.\n\n\n\n\n\nEvan Rosenman is an Assistant Professor of Statistics in the Claremont McKenna Department of Mathematical Sciences. His research focuses primarily on problems in data science and causal inference\, with applications to political science and public health. He is particularly intrigued by problems involving hybridizing observational and experimental data to better estimate causal effects\, and by applications in modern electioneering\, such as ecological inference and prediction calibration. He earned his PhD in Statistics from Stanford University and completed a postdoctoral fellowship at the Harvard Data Science Initiative.

SUMMARY:Math as Art and Recreation (Peter Kagey\, HMC)
DESCRIPTION:Title: Math as Art and Recreation \nSpeaker: Peter Kagey\, HMC \nAbstract: Recreational Mathematics is an area of math which is rooted in exploration and playfulness\, and includes puzzles\, games\, art\, and more. This talk takes a closer look at these ideas\, emphasizing how a foundation of curiosity and play can lead to insightful connections with various branches of mathematics\, fostering a deeper appreciation for both the beauty and the enjoyment inherent in mathematics. Illustrating this\, I will describe how a question from Martin Gardner ultimately led to theorems in group theory and combinatorics\, demonstrating the unexpected bridges that can be built between recreational puzzles and deeper mathematical concepts. \n\n\n\n\n\nPeter Kagey is a Visiting Assistant Professor from Harvey Mudd College. He received his Ph.D. from the University of Southern California in 2022. Since 2019\, he has been an Associate Editor with the On-Line Encyclopedia of Integer Sequences. His research interests include combinatorics and algebra\, along with discrete\, experimental\, and recreational mathematics. He is passionate about cultivating a culture of joy\, curiosity\, and care in the mathematics community.

Then I will give a brief introduction to the moduli space of curves. The study of the geometry of this moduli space has occupied several generations of mathematicians\, across fields such as algebraic and differential geometry\, mathematical physics\,  geometric group theory\, and more. Finally\, I will describe the beautiful connection between the graph complex and the topology of the moduli space. \n\n\n\n\n\nI am currently a postdoc at UCLA. I obtained my PhD from Brown University in 2023\, after graduating from Pomona College in 2018. I first became interested in the combinatorial aspects of algebraic geometry while working with Prof. Dagan Karp as an undergraduate.

SUMMARY:“The science of Mathematics is not crystallized into text-books” : The Bryn Mawr Mathematical Journal Club (1896 — 1924)\, (Jemma Lorenat\, Pitzer College)
DESCRIPTION:Title: “The science of Mathematics is not crystallized into text-books” : The Bryn Mawr Mathematical Journal Club (1896 — 1924) \nSpeaker: Jemma Lorenat\, Pitzer College \nAbstract: As mathematics departments in the United States began to shift toward standards of original research at the end of the nineteenth century\, many adopted journal clubs as forums for students to synthesize and share new research. The Bryn Mawr Mathematical Journal Club\, maintained episodically between 1896 and 1924\, began as a supplement to the graduate course offerings. Each semester student and professor participants focused on a single disciplinary area or surveyed what had been published lately. The Notebooks containing these reports were stored on the open shelves of the college library. These collectively composed documents record ways in which graduate students transcribed and interpreted contemporary mathematics. This talk focuses on the entries of Virginia Ragsdale\, in which she formulated research questions\, tested potential strategies\, and pursued novel results in topology. \n\n\n\n\n\nJemma Lorenat is a historian of mathematics at Pitzer College. She enjoys learning about the long nineteenth century\, visualization\, quantification\, ordinary people becoming mathematicians\, food\, and many other things. Her forthcoming book is about how the local environment of Bryn Mawr College shaped mathematical practices there.

SUMMARY:Adinkra Heights and Color-Splitting Rainbows (Ursula Whitcher\, American Mathematical Society)
DESCRIPTION:Title: Adinkra Heights and Color-Splitting Rainbows \nSpeaker: Ursula Whitcher\, American Mathematical Society \nAbstract: Adinkras are decorated graphs that encapsulate information about conjectural relationships between fundamental particles in physics. If we color the edges of an Adinkra with a rainbow of shades in a specific order\, we obtain a special curve that we can study usingalgebraic and geometric techniques. We use this structure to characterize height functions on Adinkras\, then show how to compute the same information using data from our rainbow. This talk describes joint work with Amanda Francis. \n\n\n\n\n\nDr. Ursula Whitcher is an associate editor at Math Reviews (MathSciNet)\, a project of the American Mathematical Society\, covering a range of areas from algebraic geometry to history of mathematics. Before joining the AMS\, Dr. Whitcher earned a PhD from the University of Washington\, was a Teaching and Research Postdoctoral Fellow at Harvey Mudd\, and became an associate professor at the University of Wisconsin-Eau Claire.

SUMMARY:Lonely Runners and My Favorite Polyhedron (Matthias Beck\, San Francisco State University)
DESCRIPTION:Title: Lonely Runners and My Favorite Polyhedron \nSpeaker: Matthias Beck\, Department of Mathematics\, San Francisco State University \nAbstract: We study the Lonely Runner Conjecture\, conceived by Wills in the 1960’s\, and originally phrased in terms of Diophantine approximation: Given positive integers n_1\, n_2\, …\, n_k\, there exists a positive real number t such that for all 1 ≤ j ≤ k the distance of t n_j to the nearest integer is at least 1/(k+1). This conjecture can be recast in lay terms: if k runners with different (constant) speeds move around a circular track of length 1\, then for each runner there will be a time when they have distance at least 1/k to the others. This (in)famous conjecture in combinatorial number theory is open for k ≥ 7.We will give a brief history of the Lonely Runner Conjecture and some of its variants\, emphasizing a view-obstruction approach by Cusick and recent work by Henze and Malikiosis; our goal is to promote a polyhedral ansatz to the Lonely Runner Conjecture. Our results include affirmative instances that become (quite literally) visible through polyhedral geometry. \nBased on joint work with Serkan Hosten (SF State) and Matthias Schymura (Rostock). \n\n\n\n\n\nMatthias Beck is a professor of mathematics at San Francisco State University and has had visiting positions at SUNY Binghamton\, the Mathematical Sciences Research Institute in Berkeley\, the Max-Planck-Institute in Bonn\, Cornell University\, Vassar College\, and the Freie Universität in Berlin. Matt’s research is in combinatorics and number theory\, in particular\, counting integer points in polyhedra and the application of these enumeration functions to various mathematical topics and problems. He (co-)authored four books and numerous research papers\, many of which feature student coauthors. Matt was honored with the Mathematical Association of America’s Haimo Award for Distinguished College or University Teaching of Mathematics in 2013.x`

SUMMARY:Slope Gap Distributions of Translation Surfaces (Taylor McAdam\, Pomona College)
DESCRIPTION:Title: Slope gap distributions of translation surfaces \nSpeaker: Taylor McAdam\, Department of Mathematics\, Pomona College \nAbstract: How “random” are the rational numbers? To make sense of this question\, let us consider the set of Farey fractions of level n—that is\, the rational numbers between 0 and 1 with denominator at most n. It turns out that these distribute uniformly in the unit interval as n goes to infinity\, which would suggest they appear to be quite random. However\, we may consider a finer test of randomness by considering the distribution of gaps between consecutive Farey fractions as n tends to infinity. To investigate this\, we will first realize the Farey fractions as the slopes of geodesic paths on the (square) flat torus—a geometric object obtained by gluing the opposite edges of a square together. We will then define the horocycle flow on the space of all flat tori\, which will allow us to study our question about gaps between Farey fractions via a dynamical system. Finally\, we will see how this method can be generalized to study the slope gap distributions for paths on a larger class of geometric objects called translation surfaces and discuss results on the collection of surfaces obtained by gluing together opposite edges of the regular 2n-gon.\n\n\n\n\n\n\nTaylor McAdam graduated with a Bachelor’s degree in mathematics from Harvey Mudd College in 2013 before starting a doctoral program at University of Texas at Austin. In 2017\, she transferred to the University of California San Diego\, where she received her PhD in mathematics in 2019 under the supervision of Amir Mohammadi. She was an NSF Postdoctoral Fellow at Yale University from 2019 to 2023\, before joining the faculty at Pomona College in 2023 as a Visiting Assistant Professor. Her research interests lie at the intersection of dynamical systems\, geometry\, and number theory\, and she is passionate about undergraduate math education and building inclusive mathematical communities.

SUMMARY:What is a moduli space? (Javier Gonzalez Anaya\, HMC)
DESCRIPTION:Title: What is a moduli space? \nSpeaker: Javier Gonzalez Anaya\, Department of Mathematics\, Harvey Mudd College \nAbstract: A natural endeavour in mathematics is to classify objects according to their properties. For example\, we can readily identify straight lines in the plane\, or recognize different kinds of triangles depending on their symmetries. Less intuitive\, however\, is that given a class of mathematical objects\, it is often possible to construct a geometric space parametrizing those objects. Known as “moduli spaces”\, the study of these spaces has been a major driving force of modern geometry. In this talk we will explore some of the main ideas behind moduli theory through examples\, ranging from the moduli space of lines in the plane to the one of points on the sphere. We will finish by discussing our ongoing research on the moduli space of points in d-dimensional space. \n\n\n\n\n\nJavier González Anaya\, PhD\, is an algebraic geometer specializing in the study of combinatorial structures and finite generation problems within the field of birational geometry. His research extends to areas such as the theory of polytopes and machine learning. Currently\, he holds a position as a visiting assistant professor at Harvey Mudd College\, having previously served in a similar role at UC Riverside. Beyond his research\, Javier is a committed educator and mentor\, having overseen student research projects and taught an extensive range of courses.

SUMMARY:Equality Cases of Geometric Inequalities (Igor Pak\, UCLA)
DESCRIPTION:Title: Equality Cases of Geometric Inequalities \nSpeaker: Igor Pak\, Department of Mathematics\, University of California\, Los Angeles \nAbstract: Geometric inequalities go back to antiquity\, and so do their equality cases.  As everyone knows\, the circle is the only case when the isoperimetric inequality is sharp.  But what happens to other geometric inequalities?  Apparently\, as the inequalities become more general\, their equality cases become more cumbersome to state and even harder to prove.  I will give a broad survey of various natural examples\, with an emphasis on discrete inequalities.  I will then explain why the celebrated Alexandrov–Fenchel inequality has intractable equality cases\, what does that mean\, and how this can be established.  The talk is aimed at a general audience.

SUMMARY:Thinking Inside the Box: A combinatorial approach to Schubert Calculus (Sami H. Assaf\, USC)
DESCRIPTION:Title: Thinking Inside the Box: A combinatorial approach to Schubert Calculus \nSpeaker: Sami H. Assaf\, Department of Mathematics\, University of Southern California \nAbstract: Given 2 lines in the plane\, how many points lie on both? If we rule out the case where the two lines are the same\, and we work in projective space so that parallel lines share the point at infinity\, then the answer is always the same: 1 point of intersection. Suppose instead we’re given 4 lines in space. How many other lines meet all four of those? Schubert asked\, and in some cases answered\, such problems in enumerative geometry in his celebrated treatise in 1879. He argued that when the answer is finite\, it does not depend on the choice of the linear spaces. Attempts to formalize Schubert’s “Principle of Conversation of Number” have led us to modern Schubert calculus and intersection theory\, which has ramifications in geometry\, topology\, combinatorics\, and even string theory. I will survey the history of this field from Schubert to now\, highlighting a partial solution that involves enumerating ways of putting numbers in boxes. \n\n\n\n\n\nSami Assaf is a Professor of Mathematics and a Gabilan Distinguished Professor of Science and Engineering at the University of Southern California. Her fundamental research in combinatorics\, geometry and probability is supported by grants from the National Science Foundation and the Simons Foundation. She has delivered plenary addresses for AMS meetings as well as for the annual Formal Power Series and Algebraic Combinatorics conference. Professor Assaf is recipient of a USC Mentoring Award for Faculty Mentoring Undergraduates\, directs a local Math Circle for elementary school students\, and currently serves as Director of Graduate Studies for the Department of Mathematics where she works to foster a culture of inclusivity\, diversity\, and excellence for all students.

SUMMARY:Building the Fan of a Toric Variety (Professor Reginald Anderson\, Claremont McKenna College)
DESCRIPTION:Title: Building the Fan of a Toric Variety \nSpeaker: Reginald Anderson\, Department of Mathematical Sciences\, Claremont McKenna College \nAbstract: Roughly speaking\, algebraic geometry studies the zero sets of polynomials\, which lead to objects called varieties. Since the zero sets of polynomials do not always pass the vertical line test\, we enlist other methods to study them besides considering the graph of a function. This is analogous to the use of implicit differentiation in calculus. One such method uses line bundles to understand a variety in terms of its algebraic subspaces. Since the zero sets of polynomials can become complicated in multiple variables over the complex numbers\, one simplifying assumption we can impose is that the variety contain a dense\, open algebraic torus. This leads to the notion of a toric variety. I will describe the fan of a toric variety for the complex projective line\, and mention some recent results concerning toric varieties. \n\n\n\n\n\nReginald Anderson received his PhD in mathematics from Kansas State University in May and studies derived categories of toric DM stacks. His research areas include algebraic geometry\, homological algebra\, and category theory.

SUMMARY:p-Norm Approval Voting (Professor Michael Orrison\, Harvey Mudd College)
DESCRIPTION:Title: p-Norm Approval Voting \nSpeaker: Michael Orrison\, Professor of Mathematics\, Harvey Mudd College \nAbstract: Approval voting is a relatively simple voting procedure: Given a set of candidates\, each voter chooses a subset of the candidates\, and the candidate chosen the most is then declared the winner. Interestingly\, approval voting can be viewed as an extreme end of a one-parameter family of voting procedures we are calling p-norm approval voting. In this talk\, I’ll explain how we were led to start studying p-norm approval voting\, and I’ll share some of the many properties we’ve discovered about it so far. This is joint work with Hari Nathan\, Katharine Shultis\, and Jessica Sorrells. \n\n\n\n\n\nMichael Orrison is a Professor of Mathematics at Harvey Mudd College. He received his A.B. from Wabash College in 1995\, and his Ph.D. from Dartmouth College in 2001. His teaching interests include linear algebra\, abstract algebra\, discrete mathematics\, and representation theory. His research interests include voting theory and harmonic analysis on finite groups. He particularly enjoys finding\, exploring\, and describing novel applications of the representation theory of finite groups with the help of his talented and energetic research students.

SUMMARY:A Brief History of Calculating Machines (Prof. Yousef Daneshbod\, University of La Verne)
DESCRIPTION:Title: A Brief History of Calculating Machines \nSpeaker: Yousef Daneshbod\, Department of Mathematics\, University of La Verne \nAbstract: Calculating machines are digital or analog devices designed to perform mathematical calculations. These machines have a long history\, with the earliest known examples dating back to ancient times\, when people used sticks and stones for counting. However\, the first mechanical calculators were invented in early modern period thanks to the theoretical development of mathematics and the growing need for more sophisticated computations. Today\, calculating machines are all around us; changing the way we live our lives. In this talk\, I will explain the evolution of early calculating machines and the key people involved with its development. \n\n\n\n\n\nDr. Yousef Daneshbod\, Associate Professor of Mathematics has been teaching at the University of La Verne since 2007. Prior to joining La Verne\, he was a Lecturer in Mathematics at Calpoly Pomona and an Adjunct Professor at Citrus College. Dr. Daneshbod received his B.S. and M.S both in mechanical engineering from Shiraz University in Iran. In the year 2001 he abandoned his studies for a PhD in mechanical engineering just one year before completion and along with his wife immigrated to the U.S. His love for mathematics motivated him to pursue a PhD degree in applied mathematics from the Claremont Graduate University\, eventually graduating in the summer of 2006. Dr. Daneshbod believes that the combination of clear classroom notes along with symbolic computer software can serve as an excellent pedagogical tool for making mathematics much more fun and intuitive for the students. His primary fields of interest include mathematical modeling in microfluidics\, theoretical and computational mechanics and wave propagation in anisotropic media. He is also interested in mathematics education in a liberal arts setting where he tries to inspire his students by exposing them to historical sketches of famous scientists and mathematicians.

SUMMARY:Sequential: A Meditation on Recurrence (Prof. Ghassan Sarkis\, Pomona College)
DESCRIPTION:Title: Sequential: A Meditation on Recurrence \nSpeaker: Ghassan Sarkis\, Department of Mathematics\, Pomona College \nAbstract: Though I will share some adventures in sequence-generating neural networks just for fun\, the majority of this talk will be concerned with Fibonacci sequences modulo $p$ and $p^2$ from data-inflected and number-theoretic perspectives\, including questions about periods of the modular sequence (how long before it repeats itself?) and associated frequencies (how many of each residue is there?) also just for fun. Most of the presentation should be understandable to math students with exposure to linear algebra and modular arithmetic\, and will include some suggested paths they may want to pursue in their own research as well. \n\n\n\n\n\nGhassan Sarkis is an Associate Professor of Mathematics & Statistics at Pomona College to his great surprise. His training is in number theory\, though he enjoys dabbling in combinatorics\, data science\, and some other puzzles that cross his path. He is very excited to discover what happens next.

SUMMARY:Wallis and Landen: A Tale of two integrals (Prof. Victor Moll\, Tulane University)
DESCRIPTION:Title: Wallis and Landen: A Tale of two integrals \nSpeaker: Victor Moll\, Department of Mathematics\, Tulane University \nAbstract: Victor Moll Abstract \n  \n\n\n\n\n\nI was born in Santiago\, Chile during the last millenium\, on October 31st. My father was a doctor in a small town. I must have been bothering my family\, so they put me to school at an early age. My first mathematical mentor was Maria Pardo\, who recognized that I had some talent for Mathematics. Since this came easy\, I spent most of my middle and high school years trying to learn some more. The other subjects suffered.\nAfter high-school\, liking Mathematics\, I enrolled in an Engineering School. Not a good idea. But since one could transfer to study Mathematics\, everything worked out fine. After graduation\, since PhD’s in Math were rare in Chile\, I was hired as a faculty member of Universidad Santa Maria (not a catholic school\, this is the last name of some rich chilean person). In 1980 I left for New York City\, to begin my graduate education at the Courant Institute of NYU. I was interested in Number Theory and this is one of the best places for Applied Mathematics. Talk about being clueless. There I met my wife\, Lisa Fauci\, then also a student. (She is the former president of SIAM and has a large collections of well-deserved awards). We both got positions at Tulane University in 1986. We figure we will try New Orleans for a year or two. Never left.\nMy PhD thesis was in the stability of waves for a model for nerve conduction. Did that until I got tenure. After tenure I spent a sabbatical to finish writing a book on Elliptic Curves (jointly with my advisor\, Henry McKean). Then a piece of luck: a first year graduate student (George Boros) told me that he could compute an integral. Not impressed\, I tried Mathematica and it was unable to find the answer. This changed my research area. I have been computing integrals since then. Have written a variety of papers on this and three books (at diverse levels). I am currently the scientific editor of the table by Gradshteyn and Ryzhik\, one of the most used tables in the world.\nI enjoy working with undergraduate and graduate students\, professional colleagues and amateurs. I have been part of REU programs such as SIMU (in Puerto Rico)\, MSRI-UP (at Berkeley) and a variety of summer programs at Tulane. Lately I have been participating in programs aimed at faculty coming from institutions with high teaching load (Park City\, Utah and ICERM\, at Brown). My latest projects involves a new method called ”The method of brackets”\, invented by my collaborator Ivan Gonzalez\, a professor of Physics in Valparaiso\, Chile. Our works deals with the evaluation of Feynman diagrams\, coming in the description of elementary particles. To me\, this is the last leg of a cycle. As a high school student\, I wanted to study Particle Physics. It is never too late to go back to the beginning.
