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.

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.

SUMMARY:Reading Topology from Open Books (Prof. Bahar Acu\, Pitzer College)
DESCRIPTION:Title: Reading Topology from Open Books \nSpeaker: Bahar Acu\, Department of Mathematics\, Pitzer College \nAbstract: How can we study topological shapes that are outside the realm of our imagination? In this talk\, we will explore potential answers to that question by diving deep into dimensionality and topology via open books.  Topology is the study of properties of shapes that do not fundamentally change when they are bent and/or stretched without poking holes or ripping apart. At this point\, you must have heard that to a topologist\, a donut and a coffee cup (with a handle) are the same thing since one can be deformed into the other continuously\, i.e. only via bending and/or stretching. A very useful strategy in studying topological objects (in our case\, manifolds) is to factor them into smaller pieces. An open book decomposition of an n-dimensional manifold (the open book) is a special function that helps us study our object in terms of its (n-1)-dimensional fibers (the pages) and (n-2)-dimensional boundary of these fibers (the binding). This topological tool provides a natural framework for studying topological properties of certain geometric structures on smooth manifolds such as contact structures. For example\, every (contact) 3-dimensional manifold can be presented as an open book whose pages are surfaces and binding is a knot/link. In this talk\, we will talk about these objects in greater detail with examples. \n\n\n\n\n\nDr. Bahar Acu is an Assistant Professor of Mathematics at Pitzer College. Prior to joining Claremont Colleges\, Dr. Acu held positions at UCLA\, Northwestern\, ETH Zürich\, and IAS Princeton following a Ph.D. degree from the University of Southern California. Dr. Acu’s primary research interests are in the field of geometric topology\, more precisely contact and symplectic topology in high dimensions and their relations with low-dimensional topology. Dr. Acu is the co-founder and lead-organizer of the inaugural international research collaboration conference for women and nonbinary mathematicians in the field of symplectic and contact geometry and topology. The peer-reviewed volume of this conference Research Directions in Symplectic and Contact Geometry and Topology\, lead-edited by Dr. Acu\, was recently published as a part of Springer’s Association for Women in Mathematics Series.

SUMMARY:How Many Cards Can Avoid a SET? (Prof. Mohamed Omar\, Harvey Mudd College)
DESCRIPTION:Title: How Many Cards Can Avoid a SET? \nSpeaker: Mohamed Omar\, Department of Mathematics\, Harvey Mudd College \nAbstract: SET is a popular real-time card game where players search for special triples of cards among a table of cards that are face-up. A common issue when playing the game is not having a SET among theface-up cards. What is the maximum number of cards that can be face-up while avoiding a SET? Surprisingly\, this question is at the heart of a decades old central problem in extremal combinatorics and additive number theory that had a major breakthrough in 2017. In this talk\, we describe the breakthrough\, and how the presenter used ideas in its development to make headway on a range of disparate problems in combinatorics. \n\n\n\n\n\nDr. Mohamed Omar is an Associate Professor of Mathematics\, Associate Chair of Mathematics and the Joseph B. Platt Chair in Effective Teaching at Harvey Mudd College. He has received national awards for his research\, including being the inaugural recipient of the American Mathematical Society’s Claytor-Gilmer Fellowship and an inaugural recipient of the Karen EDGE Fellowship\, both celebrating mid-career research. He has also earned the Henry L. Alder Award\, the preeminent junior faculty national prize given by the Mathematical Association of America. He is the author of over 30 peer-reviewed articles in internationally recognized journals\, studying the interaction between algebra and combinatorics.

SUMMARY:Sometimes Pi Equals 4 (Prof. Cornelia van Cott\, University of San Francisco)
DESCRIPTION:Title: Sometimes Pi Equals 4 \nSpeaker: Cornelia van Cott\, Department of Mathematics\, University of San Francisco \nAbstract: Most of your mathematical life\, you’ve known that pi is a number somewhere between 3.1 and 3.2. But if we exchange the usual notion of distance in two-dimensional space for others\, pi can be any of an infinite number of different values. What are these values? You’ll be surprised at the twists and turns we encounter when we head into these uncharted territories. \n\n\n\n\n\nCornelia Van Cott is a mathematics professor at the University of San Francisco. She earned her PhD from Indiana University in the area of geometric topology. Her undergraduate degree is from Wheaton College. Her current favorite work activity outside of teaching and research is doing something that combines these two things – student research projects.

SUMMARY:Watch your step: Modeling on Time Scales (Prof. Raegan Higgins\, Texas Tech University)
DESCRIPTION:Title: Watch your step: Modeling on Time Scales \nSpeaker: Raegan Higgins\, Department of Mathematics & Statistics\, Texas Tech University \nAbstract: Generally\, differential and difference equations are used in the mathematical modeling of physical systems. Our modeling approach uses dynamic equations on time scales. A time scale T is an arbitrary\, nonempty\, closed subset of the real numbers. While introducing the calculus on time scales\, we will give an application of time scales to oncology. We will discuss developing specific models and the related preliminary results and analysis. \n\n\n\n\n\nRaegan Higgins didn’t always love math. In her eyes\, it was a class that everyone had to take. It wasn’t\nchallenging\, nor was it easy; it just was. Upon placing out of Pre-Algebra in middle school\, Raegan entered Algebra which quickly became her adversary. With little Pre-Algebra background\, she struggled in the course she called “The Land of Unknowns.” But\, with a very encouraging no-nonsense teacher and parents who only asked for their daughter’s best\, Raegan excelled in Algebra and became an aspiring\nmathematician. \nIn 2008\, Raegan was one of the first two African Americans to earn a doctoral degree in Mathematics from the University of Nebraska- Lincoln. She had officially become a mathematician. In that same year\, she joined the faculty at Texas Tech University. Her primary research focuses on determining conditions in which solutions to differential-like equations eventually stay positive or negative. While also interested in applications of time scales (nonempty subsets of the real numbers)\, Dr. Higgins has a keen interest in increasing the number of women\, especially those underrepresented\, in STEM and improving the undergraduate preparation of mathematics majors. Her service mission is to support communities historically excluded from STEM by creating and supporting programs that increase visibility\, amplify the voices of women and people of color\, and foster community and share resources. Raegan serves as\ncodirector of the EDGE (Enhancing Diversity in Graduate Education) Summer Program and cofounder and cocreator of the website Mathematically Gifted and Black.

SUMMARY:Mathematical model for HIV-1 infection with stem cell and immune-therapy (Prof. Noufe Aljahdaly\, King Abdulaziz University / CGU)
DESCRIPTION:Title: Mathematical model for HIV-1 infection with stem cell and immune-therapy \nSpeaker: Noufe Aljahdaly\, Department of Mathematics\, King Abdulaziz University / CGU \nAbstract: The AIDS is a chronic disease. Its most common treatment is the antiretroviral therapy (cART) and the virus can be more effected if the patients stop using cART. The other problem is that the CD8+ T cells might be exhausted by persistent immune activation by cART. The researchers still exert their high efforts to reach the cure of HIV infection. Actually\, there are two cases that have achieved a cure of HIV-1 by stem cell (SC) transplantation who are known as London patient and Berlin patient. In this work\, we introduced the mathematical model of HIV-1 infection with stem cell therapy. The model was studied theoretically and the numerical solution was obtained to understand the effect of SC therapy. Our results realized that the virus of HIV-1 patient remains undetectable in patient blood after SC transplantation for a period of time. Then\, the patient may experience rebound within short period. These results are aligned with two medical cases in the literature. To better understand how London and Berlin patient got a cure by SC therapy while other patients did not achieve the same result\, we improved the mathematical model by taking in account the immune system response. We found that the cure of HIV-1 can be achieved by increasing the immune system response during receiving the SC therapy. \n\n\n\n\n\nNoufe is an associate professor of mathematics in the Department of Mathematics at King Abdulaziz University\, Saudi Arabia. She received her master degree in Mathematics from Oregon state University in 2012 and received her Ph.D. in Mathematics from the University of Alabama in 2017. She is a visiting researcher in CGU since Aug. 2022. Her research in applied mathematics\, mathematical modeling\, fluid dynamic and mathematical computation.

SUMMARY:Quantum chromatic numbers of products of quantum graphs (Prof. Rolando De Santiago\, Purdue University)
DESCRIPTION:Title: Quantum chromatic numbers of products of quantum graphs \nSpeaker: Rolando De Santiago\, Department of Mathematics\, Purdue University \nAbstract: Quantum graphs are an operator space generalization of classical graphs that have emerged in different branches of mathematics including operator theory\, non-commutative topology and quantum information theory. We provide a brief introduction to quantum graphs and the quantum chromatic number of graphs. We define the lexicographic product of quantum graphs and investigate the quantum chromatic number of the resulting graph products. Additionally\, we discuss our work on developing the b-fold chromatic number for quantum graphs analogous to the classical case. \nThis is joint work with Meenakshi McNamara \n\n\n\n\n\nRolando is an assistant professor of mathematics in the Department of Mathematics at Purdue University. He considers himself a proud product of the LAUSD\, the community college\, and the Cal State systems which set him up to receive his Ph.D. in Mathematics from the University of Iowa in 2017. Afterward\, he went on to do a postdoc at UCLA where he was awarded the UC Presidential Postdoctoral Fellowship in 2018. His research in the structural aspects of group von Neumann algebras sits at the intersection of analysis\, geometric group theory\, representation theory\, and\, on very rare occasions\, quantum information theory.

SUMMARY:The mathematics of neural networks: recent advances\, thoughts\, and the path forward (Prof. Mikhail Belkin\, UCSD)
DESCRIPTION:Title: The mathematics of neural networks: recent advances\, thoughts\, and the path forward \nSpeaker: Prof. Mikhail Belkin\, Department of Mathematics\, University of California San Diego \nAbstract: The recent remarkable practical achievements of neural networks have far outpaced our theoretical understanding of their properties. Yet\, it is hard to imagine that progress can continue indefinitely\, without deeper understanding of their fundamental principles and limitations. In this talk I will discuss some recent advances in the mathematics of neural networks and outline what\, in my opinion\, are some promising directions for future research. \n\n\n\n\n\nMikhail Belkin received his Ph.D. in 2003 from the Department of Mathematics at the University of Chicago. His research interests are in theory and  applications of machine learning and data analysis. Some of his well-known work includes widely used Laplacian Eigenmaps\, Graph Regularization and Manifold Regularization algorithms\, which brought ideas from classical differential geometry and spectral analysis to data science. His recent work has been concerned with understanding remarkable mathematical and statistical phenomena observed in deep learning. This empirical evidence necessitated revisiting some of the basic concepts in statistics and optimization.  One of his key recent findings is the “double descent” risk curve that extends the textbook U-shaped bias-variance trade-off curve beyond the point of interpolation. Mikhail Belkin has served on the editorial boards of the Journal of Machine Learning Research\, IEEE Pattern Analysis and Machine Intelligence and SIAM Journal on Mathematics of Data Science.

SUMMARY:Building trustworthy data-driven epidemiological models: Application to the COVID-19 outbreak in New York City (Prof. Joan Ponce\, Arizona State University)
DESCRIPTION:Title: Building trustworthy data-driven epidemiological models: Application to the COVID-19 outbreak in New York City\n\n\n\nSpeaker: Joan Ponce\, Department of Mathematics\, Arizona State University\n\nAbstract: Epidemiological models can provide the dynamic evolution of a pandemic but they are based on many assumptions and parameters that have to be adjusted over the time the pandemic lasts. However\, often the available data are not sufficient to identify the model parameters and hence infer the unobserved dynamics. We develop a general framework for building a trustworthy data-driven epidemiological model\, consisting of a workflow that integrates data acquisition and event timeline\, model development\, identifiability analysis\, sensitivity analysis\, model calibration\, model robustness analysis\, and projection with uncertainties in different scenarios.  In particular\, we apply this framework to propose a modified susceptible–exposed–infectious–recovered (SEIR) model\, including new compartments and model vaccination in order to project the transmission dynamics of COVID-19 in New York City (NYC). We find that we can uniquely estimate the model parameters and accurately project the daily new infection cases\, hospitalizations\, and deaths\, in agreement with the available data from NYC’s government’s website. In addition\, we employ the calibrated data-driven model to study the effects of vaccination and timing of reopening indoor dining in NYC.

SUMMARY:No-arbitrage Pricing in a Market for Position on a Multilane Freeway (Prof. Henry Schellhorn\, CGU)
DESCRIPTION:Title: No-arbitrage Pricing in a Market for Position on a Multilane Freeway \nSpeaker: Henry Schellhorn\, Department of Mathematics\, Claremont Graduate University \nAbstract:  We introduce a trading mechanism allowing cars to change position in a multilane congested freeway by doing peer-to-peer transactions. For the car initiating the operation\, or incoming car\, the goal can be to increase speed\, to have less speed variability\, to join a platoon\, or to join an exit lane that is slower but full. We focus in this paper on the maneuver where the incoming car changes lanes by asking an adjacent car on a busy target lane (to the left or right) to slow down\, but we also consider the case where the incoming car asks the car in front of it to change lanes\, so that the incoming car takes its position but stays on the same lane. In both cases\, the incoming car pays a transaction fee. We solve the microscopic problem of determining these transaction fees by (i) embedding the problem in a macroscopic model and (ii) calculating fair lane prices by the no arbitrage condition. This no-arbitrage condition states that no future trajectory will always be better than all others in terms of both speed and money exchanged to change lanes. The terms “always better” has to be understood in a probabilistic sense: we analyze a stochastic model\, in order to include uncertainty in both the speed model and the drivers’ decisions. We highlight the advantages of no-arbitrage theory over a traditional expected utility maximization approach. First\, no-arbitrage pricing does not require any individual data\, whether on the driver’s risk-aversion\, preference of speed over money or increased safety\, or final destination. Second\, the macroscopic model that we use considers endogenously the global impact of any individual priced transaction\, as opposed to local models that require extraneous assumptions on the road conditions after the transaction. We implemented a simple case of our priced lane change model. After simulating it extensively\, we implemented it in real-time\, with 2 cars trading position on a freeway using macroscopic speed information to determine the transaction fee. \n\n\n\n\n\nHenry Schellhorn is professor of mathematics at Claremont Graduate University’s Institute of Mathematics Sciences and academic director of the Financial Engineering Program at the Drucker School of Management. His research focuses in the areas of Monte Carlo simulation\, credit risk management\, interest rate models\, queuing theory\, and combinatorial auctions.

SUMMARY:Epidemiological models for Ebola exploring different dynamics
DESCRIPTION:In today’s environment of universal connection and media updates\, we are constantly informed about infectious diseases and the ramifications. We can combat infectious diseases using mathematics to gain insight into diseases dynamics and outbreaks. I will focus primarily on Ebola Virus Disease\, exploring different models focused on capturing various dynamics.\nFirst\, I will present a model whose goal is to illustrate role of education in limiting a potential future Ebola outbreaks in Sudan using data and modeling. Then\, I will introduce a model which captures superspreader dynamics and compare the model for Ebola and Middle Eastern Respiratory Syndrome (MERS). In addition to these models I will explain about how I became interested in Mathematical Epidemiology and some of the great programs which have led to my research collaborations.

SUMMARY:A geospatial modeling analysis of travel-time\, bicycles\, and HIV elimination in sub-Saharan Africa: the case of Malawi
DESCRIPTION:UNAIDS has proposed an ambitious strategy for ending the HIV pandemic. Their strategy depends upon achieving a treatment coverage goal of 90% by 2030. However\, distance to healthcare and lack of transportation are major barriers to accessing HIV treatment in SSA. I will use data-based geospatial modeling to determine their potential impact as barriers to elimination in Malawi. I will address two specific questions: How much time would people living with HIV (PLHIV) need to spend travelling to access treatment in order for Malawi to achieve UNAIDS’ goal of 90% coverage? Could providing bicycles to rural communities help eliminate HIV?\nOur results show that it will only be possible to achieve UNAIDS’ 90% coverage goal in Malawi if many of the PLHIV (who have yet to initiate treatment) are willing\, and able\, to spend a great deal of time travelling to access treatment. Additionally\, they show that making bicycles available to PLHIV in rural areas has the potential to make the 90% target goal more attainable\, and hence to help eliminate HIV in Malawi.

SUMMARY:Silica-based glasses: Realizing process-structure-property connections through computational modeling
DESCRIPTION:Silica-based glasses are increasingly becoming vital components in our current technology\, from optical data transmission lines\, to electronics\, to optical lenses\, to smartphone screens. These materials are inherently brittle and subject to failure under shock\, non-equilibrium stress states\, or corrosive environments.  Identifying new compositions and processing conditions that result in improved fracture resistance (i.e. a higher fracture toughness) is achievable through materials design approaches. However\, discovery primarily remains an empirically determined procedure.  Atomistic molecular dynamics can be a powerful tool in this application\, providing a capability to probe how glass breaks and what compositions or microstructural features result in better material performance.  In this talk\, a novel numerical method to determine the fracture toughness from atomistic material representations will be demonstrated on vitreous silica-based glass compositions. Process-structure-property connections will then be explored using this measure to highlight the relationships between processing conditions\, chemical composition\, microstructural content\, and material performance.  Finally\, an overview of the collaboration between the 2019-20 CGU Math Clinic team and Sandia National Laboratories will be discussed\, where project goals are focused on using machine learning to predict fracture nucleation in silica glass.  \nSandia National Laboratories is a multi-mission laboratory managed and operated by National Technology and Engineering Solutions of Sandia\, LLC.\, a wholly owned subsidiary of Honeywell International\, Inc.\, for the U.S. Department of Energy’s National Nuclear Security Administration under contract DE-NA0003525.

SUMMARY:Science for the Greater Good: How a Math Professor Saved the Italian Coastline from Big Oil
DESCRIPTION:In 2007\, Dr. Maria D’Orsogna learned of proposed oil activities in her home region of Abruzzo\, Italy. Century-old wineries were to be uprooted to build clusters of oil wells\, refineries and pipelines\, turning scenic Abruzzo into an oil district. Although based in California\, 6\,000 miles away\, Dr. D’Orsogna took it upon herself to raise awareness and educate the public at large. She blended her scientific training\, her experience as a professor\, and her strong desire for social justice into an environmental movement that rapidly spread from Abruzzo across the country. Over the years\, she traveled from town to town in Italy\, educating citizens about environmental and health effects tied to hydrocarbon extraction\, debating Big Oil\, exposing political corruption\, engaging the Catholic Church\, putting pressure on decision makers to act for the common good. While in California she used social networks and blogging to expose wrongdoings of the oil and gas industry\, coordinate letter writings\, keep raising awareness and spur action. Thanks to public uproar\, spearheaded by Marias unwavering efforts\, Abruzzo banned oil drilling and for the first time ever\, the Italian parliament imposed a no-drill zone of 12 miles encompassing all of Italy’s 5\,000 mile coastline. Overall she helped stop at least 50 oil leases\, earning the nickname Erin Brockovich of Italy. Maria’s story is a testament of how\, by engaging with the community\, scientists and educators can truly make a difference.

SUMMARY:Calculus\, Real Fewnomials\, and P vs NP
DESCRIPTION:We review a beautiful 17th century result by the philosopher Rene Descartes: a univariate real polynomial with t monomial terms has no more than t-1 positive roots. We then see how one can prove a generalization that counts roots of two bivariate polynomials (with few monomial terms)\, using nothing more than basic calculus. In other words\, we’ll see the basics of real fewnomial theory. We’ll then see how this relates to circuit complexity and the famous P vs. NP Problem. In particular\, we’ll see how new bounds in real fewnomial theory lead to new separations of complexity classes that answer deep questions in theoretical computer science. Along the way\, we’ll see some of the ideas behind tropical geometry.

SUMMARY:Magnitude meets persistence. What happens after?
DESCRIPTION:The magnitude is an isometric invariant of metric spaces that\nwas introduced by Tom Leinster in 2010\, and is currently the object of\nintense research\, as it has been shown to encode many invariants of a\nmetric space such as volume\, dimension\, and capacity. When studying a\nmetric space in topological data analysis using persistent homology\, one\napproximates the space through a nested sequence of simplicial complexes\nso as to recover topological information about the space by studying the\nhomology of this sequence. In this talk I will give an introduction to\nmagnitude as well as persistent homology\, and explain how magnitude\nhomology is related to persistent homology.
