SUMMARY:Emer Lopera Arias (HMC)
DESCRIPTION:Title: The fractional p-Laplacian operator. Motivation for its definition and related boundary value problems \nAbstract: \nLast decades\, nonlocal operators\, as the fractional Laplacian\, have gained to much attention due to its applications to several physical Phenomena. In this talk we aim to motivate the definition of the fractional laplacian operator through a simple but quite illustrative example related to Long jump random walks. then\, we will present a generalization to the fractional p-laplacian operator\, p>1\, and we will show a new result concerning the existence of solutions for a boundary value problem with this operator.

SUMMARY:Negligible cohomology (Matthew Gherman\, Caltech)
DESCRIPTION:For a finite group G\, a G-module M\, and a field F\, an element u in H^d(G\,M) is negligible over F if for each field extension L/F and every continuous group homomorphism from Gal(L^{sep}/L) to G\, u is in the kernel of the induced homomorphism H^d(G\,M) to H^d(L\,M). Negligible cohomology was first introduced by Serre and has deep connections with the embedding problem\, cohomological invariants\, and the profinite inverse Galois problem. Professor Alexander Merkurjev (UCLA) and I were able to compute negligible cohomology in degree 2\, compute the mod p negligible cohomology of elementary abelian p-groups\, and determine the Krull dimension of the quotient of mod p cohomology by the ideal of negligible elements.

SUMMARY:Claremont Topology Seminar: Elena Wang (Michigan State University)
DESCRIPTION:We welcome all undergraduates and graduate students to attend topology seminar! \nSpeaker: Elena Wang (Michigan State University) \nTitle: A Distance for Geometric Graphs via the Labeled Merge Tree Interleaving Distance \nAbstract: Geometric graphs appear in many real-world data sets\, such as road networks\, sensor networks\, and molecules. We investigate the notion of distance between graphs and present a metric to measure the distance between two geometric graphs via merge trees. In order to preserve as much useful information as possible from the original data\, we introduce a way of rotating the sublevel set to obtain the merge trees via the idea of the directional transform. We represent the merge trees using a surjective multi-labeling scheme\, and then compute the distance between two representative matrices. Our distance not only has theoretically desirable qualities but can also be approximated in polynomial time. We illustrate its utility by implementation on a Passiflora leaf data set.

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:Lattice angles and quadratic forms (Lenny Fukshansky\, CMC)
DESCRIPTION:What are the possible angles between two integer vectors in R^n? If we fix one such possible angle and one integer vector x\, is there always another integer vector y that makes this angle with x? Assuming that x makes a given angle with some vector\, how can we find the shortest such vector y? What if we designate a forbidden set of vectors\, what is the shortest y making a given angle with x outside of this forbidden set? It turns out that all of these questions can be reformulated in terms of a search for zeros of integral quadratic forms\, a rich arithmetic theory. We will give an introduction to this research direction and also show some of our recent results. Joint work with Sehun Jeong (CGU).

SUMMARY:Applied Math Seminar: Christina Edholm (Scripps College)
DESCRIPTION:Title:    Controlling the unmanageable: insight into control methods for biological systems \nAbstract:\nWhen formulating a model for a biological system\, often we want to use the model to understand the implications of management options and how to optimize the implementation. There are various methods for implementing management through control theory\, ranging from basic\, optimal control\, adaptive control\, and more. We will discuss the different options for utilizing control for biological systems\, and when these different methods make the most sense. The applications focus on invasive species and epidemiology but can be broadened to various other applications.

SUMMARY:Localization techniques in equivariant cohomology (Reginald Anderson\, CMC)
DESCRIPTION:In order to understand a topological space X\, it is often easier to understand X in terms of an action by a group G. When X is a compact complex manifold\, we often let G be products of S^1 or \C^* acting in a nice way (“holomorphically”) on X. This simplifies several calculations of an Euler characteristic by considering the torus-fixed loci; examples are given throughout.\n\nThe notes for this talk can be found here:\n\nhttps://drive.google.com/file/d/1FjhKDeJLIPQBlLA-x-BsnkosNayZMSAn/view?usp=sharing

SUMMARY:Claremont Topology Seminar: Migiwa Sakurai (Shibaura Institute of Technology)
DESCRIPTION:We welcome all undergraduate/graduate students and faculty to attend topology seminar! \nSpeaker: Migiwa Sakurai (Shibaura Institute of Technology) \nTitle: Clasp pass moves and arrow polynomials of virtual knots \nAbstract: For classical knots\, clasp pass moves are closely related to Vassiliev invariants of degree 3. Tsukamoto showed that the values of the Vassiliev invariant of degree 3 induced from the Jones polynomial for two knots differ by 0 or +36/-36\, if they are related by a single clasp pass move. For virtual knots\, the arrow polynomial is a generalization of the Jones polynomial and induces a Vassiliev invariant of degree 3. We show that the values of the Vassiliev invariant of degree 3 induced from the arrow polynomial of two virtual knots differ by 0 or +2304/-2304\, if they are related by a single clasp pass move. We also obtain a lower bound of the distance between virtual knots by clasp pass moves.

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:Analysis seminar: Gerald Beer (CSULA)
DESCRIPTION:Title: A crash course in Bornologies \nAbstract: By a bornology on a nonempty set X\, we mean a family of subsets that contains the singletons\, that is stable under finite unions\, and that is stable under taking subsets. The prototype for a bornology is the so-called metric bornology: the family of metrically bounded subsets of a metric space. Bornologies help us to understand large structure. We enumerate some basic bornologies and give a few applications. We give an old result of S.-T. Hu characterizing the bornologies on a metrizable space that are metric bornologies with respect to some compatible metric\, and give a fairly recent result of J. Cabello-Sanchez characterizing those metric spaces (X\,d) for which UC(X\,R) is a ring. We introduce the notion of bornological convergence of a sequence or net of closed subsets\, of which Attouch-Wets convergence is the prototype\, and give two applications to functional analysis.

SUMMARY:Presentations of derived categories (Reginald Anderson\, CMC)
DESCRIPTION:A modification of the cellular resolution of the diagonal given by Bayer-Popescu-Sturmfels gives a virtual resolution of the diagonal for smooth projective toric varieties and toric Deligne-Mumford stacks which are a global quotient of a smooth projective variety by a finite abelian group. In the past year\, Hanlon-Hicks-Lazarev gave a minimal resolution of the diagonal for toric subvarieties of smooth projective toric varieties. We give implications for exceptional collections on smooth projective toric Fano varieties in dimensions 1-4. This is joint work with CMC undergrads Justin Son\, Hill Zhang\, and Jumari Querimit-Ramirez.

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:Applied Math Seminar: Sarah Marzen (Department of Natural Science)
DESCRIPTION:Title: How well do neurons\, humans\, and artificial neural networks predict? \nAbstract: Sensory prediction is thought to be vital to organisms\, but few studies have tested how well organisms and parts of organisms efficiently predict their sensory input in an information-theoretic sense.  In this talk\, we report results on how well cultured neurons (“brain in a dish”) and humans efficiently predict artificial stimuli. We find that both are efficient predictors of their artificial input.  That leads to the question of why\, and to answer this\, we study artificial neural networks\, finding that LSTMs show similarly efficient prediction but do not model how humans learn well.  Instead\, it appears that an existing model of cultured neurons and a model of humans as order-R Markov modelers explain their performance on these prediction tasks.

SUMMARY:Adinkras as Origami? (Edray Goins\, Pomona College)
DESCRIPTION:Around 20 years ago\, physicists Michael Faux and Jim Gates invented Adinkras as a way to better understand Supersymmetry.  These are bipartite graphs whose vertices represent bosons and fermions and whose edges represent operators which relate the particles.  Recently\, Charles Doran\, Kevin Iga\, Jordan Kostiuk\, Greg Landweber and Stefan M\'{e}ndez-Diez determined that Adinkras are a type of Dessin d’Enfant; they showed this by explicitly exhibiting a Belyi map as a composition $\beta: S \to \mathbb P^1(\mathbb C) \to \mathbb P^1(\mathbb C)$.  They computed the first arrow as a map from a certain compact connected Riemann surface $S$ to the Riemann sphere $\mathbb P^1(\mathbb C) \simeq S^2(\mathbb R)$\, and the second as a map which keeps track of the “coloring” of the edges.\n\nAdinkras naturally have square faces.  This keeps track of the non-commutative nature of the supersymmetric operators.  While Dessin d’Enfants correspond to triangular tilings of Riemann surfaces\, there is a similar construction — called “origami” — which correspond to square tilings.  In this project\, we attempt to discover how to express the construction of Doran\, et al. as a composition $\beta: S \to E(\mathbb C) \to \mathbb P^1(\mathbb C)$ for some elliptic curve elliptic curve $E$ such that the map corresponds to an “origami”\, that is\, a map which is branched over just one point.  This work is conducted as part of the Pomona Research in Mathematics Experience (DMS-2113782).

SUMMARY:Claremont Topology Seminar: Reginald Anderson (CMC)
DESCRIPTION:We welcome all undergraduate/graduate students and faculty to attend topology seminar! \nSpeaker: Reginald Anderson (CMC) \nTitle: Presentations of derived categories \nAbstract: A modification of the cellular resolution of the diagonal given by Bayer-Popescu-Sturmfels gives a virtual resolution of the diagonal for smooth projective toric varieties and toric Deligne-Mumford stacks which are a global quotient of a smooth projective variety by a finite abelian group. In the past year\, Hanlon-Hicks-Lazarev gave a minimal resolution of the diagonal for toric subvarieties of smooth projective toric varieties. We give implications for exceptional collections on smooth projective toric Fano varieties in dimensions 1-4. This is joint work with CMC undergrads Justin Son\, Hill Zhang\, and Jumari Querimit-Ramirez.

SUMMARY:Analysis seminar: Stephan Ramon Garcia (Pomona College)
DESCRIPTION:Title: What can chicken McNuggets tell us about symmetric functions\, positive polynomials\, random norms\, and AF algebras? \nAbstract: Numerical semigroups are combinatorial objects that lead to deep and subtle questions. With tools from complex\, harmonic\, and functional analysis\, probability theory\, algebraic combinatorics\, and computer-aided design\, we answer virtually all asymptotic questions about factorization lengths in numerical semigroups. Our results yield uncannily accurate predictions\, along with unexpected results about symmetric functions\, trace polynomials\, and the statistical properties of certain AF C∗-algebras. \nWork partially supported by NSF Grants DMS-1800123 and DMS-2054002.

SUMMARY:GEMS October 5th Session
DESCRIPTION:Title:  How to use coins to make a 7-sided die\n\nAbstract:  Certain dice are easier to make than others.  There is the standard 6-sided die\, but 4-sided\, 8-sided\, 10-sided\, 12-sided\, and 20-sided are also very common.  What isn’t so common is a 7-sided die.  Here Dr. Mark Huber from Claremont McKenna College will talk about how you can simulate a roll of a 7-sided die using only flips of a fair coin.  This works because of something called the Fundamental Theorem of Perfect Simulation\, which allows us to break down simulation problems into smaller problems.

SUMMARY:Counting matrix points via lattice zeta functions (Yifeng Huang\, USC)
DESCRIPTION:​I will introduce two general problems and explain how they surprisingly connect with each other and with other aspects of mathematics (for a glimpse\, Sato—Tate\, hypergeometric functions\, moduli spaces of sheaves\, Catalan numbers\, Hall polynomials\, etc.)​.\n\nThe first problem is to count finite-field points on so called “varieties of matrix points”. They are created from a simple and fully elementary recipe and can yet easily get very complicated. The second problem is analogous to counting full-rank sublattices of $\mathbb{Z}^d$ with index $n$\, but with $\mathbb{Z}$ replaced by non-Dedekind rings\, such as non-maximal orders in number fields.

SUMMARY:What Happens when Our Perspectives Don’t Align with the Math?  (Anne Cawley\, Cal Poly Pomona)
DESCRIPTION:Speaker: Anne Cawley\, Associate Professor of Mathematics and Statistics\, Cal Poly Pomona\, CA \nTitle: What Happens When Our Perspectives Don’t Align with the Math? \nAbstract: Many people often share that they like math because there is “one right answer” and is an objective field. Once they find the answer\, they are done with a problem. However\, what happens when we complete our mathematical work but we choose to ignore what that work tells us? This talk discusses my experience teaching a lesson within a Teaching Math for Social Justice course related to a recent Supreme Court case on voting rights. Many students used mathematics to support an argument that the Supreme Court made in a February hearing\, however\, due to their personal perspectives\, provided a conclusion that differed from what the math indicated. This talk shares about the tensions that can arise when considering math and social justice. \nBio: Anne Cawley is an associate professor of Mathematics and Statistics at Cal Poly Pomona. Her research in Mathematics Education relates to equity\, specifically to classroom experiences of historically underrepresented students\, sense of belonging\, and math instruction in the first two years of college. She provides professional development for mathematics faculty at toward equity-minded teaching practices. Anne is the course coordinator for co-requisite mathematics courses at Cal Poly Pomona\, working with various campus partners for student success. She is also an active member in various mathematics education organizations such as AMATYC\, RUME\, and MESCal. \n  \n

SUMMARY:Analysis Seminar: Domains of Quantum Metrics on AF algebras (Katrine von Bornemann Hjelmborg\, University of Southern Denmark (SDU))
DESCRIPTION:Title: Domains of Quantum Metrics on AF algebras \nAbstract: Given a compact quantum metric space (A\, L)\, we prove that the domain of L coincides with A if and only if A is finite-dimensional. Intuitively\, this should allow for different quantum metrics with distinct domains when A is infinite-dimensional\, and we show how to explicitly build such quantum metrics. Lastly\, we also provide a strategy for the calculation of distance between certain states in these quantum metrics in the special cases of the quantized interval and the Cantor space. This is joint work with Konrad Aguilar and Frédéric Latrémolière.

SUMMARY:Applied Math Seminar: Ruijun Zhao (Claremont McKenna College)
DESCRIPTION:Title: Mathematical models studying the effectiveness of control strategies for malaria \nAbstract: According to the 2023 World Malaria Report: Nearly half the world’s population lives in areas at risk of malaria transmission in 85 countries and territories. In 2022\, malaria caused an estimated 249 million clinical episodes\, and 608\,000 deaths. In this talk\, we will discuss a few mathematical models that study the effectiveness of control strategies such as vaccines and insecticide-treated bednets. We will also discuss a model to understand the interplay between malaria dynamics\, economic growth\, and transient events. The challenges when conducting mathematical analysis and numerical simulation will also be discussed.

SUMMARY:Making sandwiches: a novel invariant in D-module theory (David Lieberman\, HMC)
DESCRIPTION:In the field of commutative algebra\, the principal object of study is (unsurprisingly) commutative algebras. A somewhat unintuitive fact is that results about commutative algebras can be gleaned from an associated non-commutative algebra whose generators are very analytic in nature. This object is called the ring of differential operators\, often denoted by D. In a sense gives an algebraic way of constructing the partial derivative.\n\nAn important result in the study of D-modules is Bernstein’s inequality\, first proved by Joseph Bernstein in the 1970’s. The result gives a lower bound on the filtered dimension of a D-module\, which a provide insights about modules of commutative algebras. The goal of this talk is to present some novel singular settings where this inequality holds. To do this\, we will introduce an invariant called sandwich Bernstein-Sato polynomials. These are analogous to a well studied object called the Bernstein-Sato polynomial\, which is a generalization of the power rule taught in undergraduate calculus courses. Using sandwich Bernstein-Sato polynomials\, we will show that Bernstein’s inequality holds true for the differential operators of the coordinate ring of the Segre product of projective spaces.
