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.

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.

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.
