These rhythms can be self-sustained (for example\, people still show circadian patterns even in total darkness)\, but they are also strongly influenced by the environment\, especially light. Mathematical models of circadian rhythms have provided insight into many intriguing phenomena\, including jet lag\, mid-afternoon fatigue\, and how animals sense the changing seasons. In this talk\, I will introduce how mathematical models of circadian rhythms are constructed and used. Then\, I will share recent work on seasonal timing in a large population of medical interns\, using data collected from wearable devices. Our results suggest that seasonal timing plays a key role in how people respond to shift work. Overall\, the goal of this talk is to introduce how mathematical modeling can be used to better understand biological rhythms and their impact on daily life.\n \nBio: I am originally from Koreatown\, Los Angeles. I did my undergraduate studies at Pomona College (Class of ’17)\, where I majored in math and completed a thesis under the mentorship of Dr. Ami Radunskaya. I enjoyed teaching mathematics and doing research\, so I decided to pursue graduate studies in math at Duke University. During my PhD\, I fell in love with biological rhythms and mathematical neuroscience. Currently\, I am a postdoc at the University of Michigan using mathematical modeling and data science to study biology and health. During my free time\, I enjoy playing pool\, hanging out with my dog\, and reading.

As such\, it allows one to determine whether certain integer polynomials have a root mod p. The Langlands program is a vast area of current research in number theory that can be viewed as a generalization of class field theory to all integer polynomials. In this talk\, I will give a leisurely introduction to this circle of ideas by way of some concrete examples. I will conclude with my own work\, which includes a result on the independence of the cohomology theory chosen in a geometric and categorical analogue of the Langlands program.\n \nBrief Bio: Robert Cass joined the Mathematical Sciences Department at CMC as an Assistant Professor of Mathematics this fall. He received his B.S. from the University of Kentucky and his Ph.D. from Harvard University. After that\, he was an NSF postdoctoral fellow at Caltech and the University of Michigan. He is interested in the Langlands program and arithmetic geometry\, as well as related problems in algebraic geometry and representation theory. He enjoys mathematical questions that are simple to state but whose solutions involve tools from multiple disciplines\, especially those with unexpected connections to geometry.

Bernoff\, Harvey Mudd College\, CA) DESCRIPTION:Speaker: Andrew J. Bernoff\, Professor of Mathematics\, Harvey Mudd College \nAbstract: An outstanding challenge in mathematical biology is using laboratory and/or field observations to tune a model’s functional form and parameter values. These problems lie at the intersection of dynamical systems and data science. In this talk I will discuss an ongoing project developing models of the Australian plague locust for which excellent field data is available. Under favorable environmental conditions flightless juveniles aggregate into coherent\, aligned swarms referred to as hopper bands. We develop two models of hopper bands in tandem; an agent-based model that tracks the position of individuals and a continuum model describing locust density. By examining 4.4 million parameter combinations\, we identify a set of parameters that reproduce field observations. \nI will then discuss ongoing efforts to improve these models. The first extends this work by modeling locust alignment via the Kuramoto model of oscillator synchronization. The second uses motion tracking of tens of thousands of locusts to shed light on how locust movement is influenced by social interactions. \n  \nBio: Andrew Bernoff is a Professor of Mathematics whose research focuses on applying dynamical systems to physical and biological phenomena\, with notable international recognition for his work on swarming. He earned degrees in math and physics from MIT and a  PhD from the University of Cambridge as a Marshall Scholar. With over 50 published papers and multiple NSF and Simons Foundation grants\, his interdisciplinary collaborations span physics\, engineering\, chemistry\, and biology. \nA dedicated educator\, Bernoff has mentored over 60 undergraduate research projects at Harvey Mudd College\, with many students pursuing PhDs at top institutions. He has served in leadership roles including Director of the Claremont Center for Mathematical Sciences\, Chair of the SIAM Dynamical Systems Group\, and a co-author of the Putnam Exam (2019–2021).

Investigations of the factors which contribute to student success along various dimensions\, how to improve student success\, and how to implement successful interventions at scale reveal the complexities of the STEM higher education ecosystem as well as the critical role of introductory mathematics courses. I will review results along these themes\, highlighting interactions which define that ecosystem and support/constrain different aspects of student success\, for different populations. This includes the role of intra- and extra-curricular factors such as student-student interactions\, course coordination\, departmental culture\, and instructors’ beliefs. Implications for research and practice will also be discussed. \nBio: Dr. Naneh Apkarian is an Assistant Professor in the School of Mathematical and Statistical Sciences at Arizona State University. She is from California\, where she obtained a BA and MA in mathematics prior to completing her PhD in mathematics education. Pursuing departmental change as a strategy for transforming mathematics education\, she was for two years a postdoctoral researcher at Western Michigan University. Her research spans many facets of the STEM education ecosystem\, including the knowledge\, beliefs\, practices\, and experiences of students and instructors\, departmental culture\, and interactions within and across levels – always in the service of building inclusive excellence. Outside academia\, Dr. Apkarian continues to play competitive water polo across the US and the world. \n  URL:https://colleges.claremont.edu/ccms/event/ccms-colloquium-naneh-apkarian-arizona-state-university-arizona/ LOCATION:Argue Auditorium\, Pomona College\, 610 N.

The sample function of Brownian motion is nowhere differentiable and generates various interesting fractal sets and measures. It is natural to apply tools from Fractal Geometry (e.g. Hausdorf dimension\, packing dimension) to study the fine properties of Brownian motion. There is an enormous literature on sample path properties of Brownian motion\, including many fractal and multifractal properties.\nIn this talk\, we first provide an overview of some regularity and fractal properties of Brownian motion and its local times. These results are fundamental for the development of related theories for other stochastic processes. We then describe extensions of these results to Levy stable processes and fractional Brownian motion\, which are two important relatives of Brownian motion in the areas of Markov processes and Gaussian processes\, respectively. \nBio: Yimin Xiao is an MSU Research Foundation Professor in Statistics and Probability at Michigan State University. He received his Ph.D. from the Ohio State University in 1996. After completing his postdocs at the University of Utah and Microsoft Research\, he joined Michigan State University in 2000. His research interests include random fields\, Gaussian and Lévy processes\, stochastic partial differential equations\, extreme value theory\, random fractals\, and statistical analysis of spatial and spatio-temporal models. He has published about 160 articles in peer-reviewed journals. \nDr. Xiao has been a visiting professor at several universities in China\, France\, Germany\, Hong Kong\, Sweden\, and Switzerland and has been invited as a speaker at various international conferences. He is a Fellow of the Institute of Mathematical Statistics. \n  URL:https://colleges.claremont.edu/ccms/event/ccms-colloquium-brownian-motion-random-fractals-and-beyond-yimin-xiao-michigan-state-uni/ LOCATION:Argue Auditorium\, Pomona College\, 610 N.

In two dimensions\, symplectic geometry is equivalent to volume-preserving geometry\, but in higher dimensions\, Gromov proved in volume inequality is not enough to guarantee embedding. In this talk\, we will explain an example for which requiring the complement of the embedding to contain a symplectic surface with fixed boundary conditions (the so-called “anchor”) provides an even stronger restriction than the symplectic form alone. The result is joint work with Michael Hutchings\, Agniva Roy\, and Yuan Yao; the method of proof that will be shown is ongoing work with Hutchings\, Roy\, and Yao and uses 2-parameter persistence modules\, a tool from topological data analysis which we will review.

In this talk\, we examine how these local individual-based mechanisms translate into global population dynamics. In particular\, we will consider the Allee effect in population models\, which were originally proposed to describe population dynamics that cannot be explained by exponential and logistic growth models. Using stochastic individual-based models\, we can obtain a modelling framework that translates particular global Allee effects to specific individual-based mechanisms. This modelling framework is then extended to applications in the social sciences\, including the modelling of sports riots and panic-buying. \nBio: Nabil  Fabir is an assistant professor at the University of Nottingham\, whose research focuses on employing reaction-diffusion equations and agent-based modelling to describe physical phenomena in a variety of applications. Originally from the west coast of Canada\, Nabil completed his PhD in the Industrially Focused Mathematical Modelling doctoral training centre at the University of Oxford in 2018. He worked as a postdoctoral researcher at the Queensland University of Technology in Brisbane\, Australia\, and has been at Nottingham since 2020. In addition to his research in industrial mathematics and mathematical biology\, Nabil is passionate about inclusive curriculum and accessible teaching to undergraduate students. \n  URL:https://colleges.claremont.edu/ccms/event/ccms-colloquium-nabil-fadai-university-of-nottingham/ LOCATION:Argue Auditorium\, Pomona College\, 610 N.

DESCRIPTION:Speaker: Hrushikesh Mhaskar\, Distinguished Research Professor of Mathematics\, Claremont Graduate University \nTitle: Local Analysis Of Global Data \nAbstract: For a periodic integrable function f\, the definition of Fourier coefficients requires the values of f on the entire period.\nWe refer to such data as “global” data. Even though the sequence of Fourier coefficients determines f uniquely\,\nthey do not reveal by themselves local features such as the locations of discontinuities of f (whose definition requires\nthe values of f locally near the point of discontinuity). We will describe our work for extracting such local features\nfrom global data. We will discuss some modern applications such as the separation of blind source signals\, and\nmachine learning problems\, classification and regression in particular. \nBio: Hrushikesh Mhaskar is a research professor of mathematics. He holds a PhD in mathematics\, MS in computer science\, and MS in mathematics from Ohio State University\, and an MSc in mathematics from Indian Institute of Technology\, Mumbai. \nMhaskar’s area of research is approximation theory and harmonic analysis. He has done pioneering work in the theory of weighted polynomial approximation on the real line\, making deep contributions in the areas of orthogonal polynomial expansions and applications of potential theory to the study of orthogonal polynomials\, now known as Freud polynomials. This work is recognized through such terms as Mhaskar-Rahmanov-Saff number and Mhaskar-Saff functional. Since 1990\, he has been interested in machine learning and signal processing\, making pioneering contributions to the theory of approximation capabilities (expressive power) of shallow and deep neural networks\, kernel-based methods\, and manifold learning. He has published two books\, five edited volumes\, and over 150 refereed papers. His research is supported currently by the National Science Foundation\, and previously by the U.S. Air Force\, U.S. Army\, and Office of the Director of National Intelligence (U.S.A.). \nMhaskar serves on the editorial boards of Applied and Computational Harmonic Analysis\, Journal of Approximation Theory\, Frontiers in Applied Mathematics and Statistics\, Jaen Journal of Approximation\, and Mathematical Foundations of Computing.

However\, before college\, access to challenge and rigor is often limited to those from privileged backgrounds\, relying on paying for special programs or having strong community knowledge to find the right programs. \nHow\, then\, can we enhance access to high-quality preparation in STEM? In this talk\, I will share some reflections on the work to be done\, and how we are approaching that work at Bridge to Enter Advanced Mathematics (BEAM). BEAM creates pathways for students from low-income and historically marginalized communities to become scientists\, mathematicians\, engineers\, and computer scientists. What we’ve seen is clear: many more students can thrive with the right combination of support and access. With a thoughtful approach\, we can make real progress. \nBio: Dan Zaharopol is the Founder and CEO of Bridge to Enter Advanced Mathematics (BEAM). An award-winning teacher and nonprofit entrepreneur\, Dan’s work at BEAM has been featured in the New York Times\, Education Week\, the Notices of the American Mathematical Society\, and the Atlantic Monthly\, among others\, and he’s shared his work through articles and talks in a variety of settings.  But more importantly (at least to him)\, Dan loves math\, sharing math\, and mentoring and supporting students\, and he’s worked with enrichment programs supporting students from all backgrounds across the country.

In extremal set theory\, often the aim is to find the largest or smallest collection of subsets with a specific property. Using the lens of partially ordered sets\, one can investigate vector spaces over finite fields using vaguely similar techniques. If V is an n-dimensional vector space over a finite field\, then how many k-dimensional subspaces can you find so that your collection does not include three distinct subspaces A\, B\, and C with A = (A\cap B) \oplus (A \cap C)? How many subspaces of any dimension can you find so that your collection does not include three distinct subspaces A\, B\, and C with either $A  \subseteq B \cap C$ or $B+C \subseteq A$? These puzzles will illustrate the connections between combinatorics of finite sets and of vector spaces. \nBio:  Shahriari is the William Polk Russell Professor of Mathematics at Pomona College. He has had the privilege of teaching/mentoring generations of talented students\, many of whom are now teaching in universities and colleges across the country. \nIn 2015\, Shahriar Shahriari received a Mathematical Association of America Deborah and Franklin Tepper Haimo Award for Distinguished Teaching in Mathematics for his commitment to bringing more students from underrepresented groups into the field of mathematics — widely considered the nation’s top prize for teaching mathematics.

Przytycki\, and independently by Vladmimor Turaev\, as generalisations of the Jones\, Kauffman bracket\, and HOMFLYPT polynomial link invariants in the 3-sphere to arbitrary 3-manifolds. The Kauffman bracket skein module (KBSM) is the most extensively studied of all. However\, computing the KBSM of a 3-manifold is known to be notoriously hard\, especially over the ring of Laurent polynomials. Marche conjectured that over the ring of Laurent polynomials\, the KBSM of closed oriented 3-manifolds splits into the sum of free and torsion modules. The counterexample to this conjecture is given by the connected sum of two copies of the real projective space. With the goal of finding a definite structure of the KBSM over this ring\, we compute the skein module of S^1 x S^2 # H_1 and S^1 x S^2 # S^1 x S^2. We show that it is isomorphic to the KBSM of a genus two handlebody modulo some specific handle sliding relations. Moreover\, these handle sliding relations can be written in terms of Chebyshev polynomials. We also discuss whether the KBSM of these manifolds splits into the sums of free and torsion modules. This is joint work with Seongjeong Kim\, Shangjun Shi\, and Xiao Wang.

The homological mirror symmetry (HMS) conjecture was originally formulated by M. Kontsevich in 1994 to fully capture this phenomenon for mirror pairs of compact Calabi-Yau manifolds. Since then\, it has been extended to cover a much wider range of manifolds. For example\, in 2 real dimensions\, among the compact Riemann surfaces\, the torus is Calabi-Yau\, the sphere is Fano\, and all others are of general type; in addition\, there are punctured Riemann surfaces which are not compact. In this talk\, I will present a few illustrative examples of HMS\, including ones worked out by others and from my own research.

DESCRIPTION:Speaker: Dorothy Buck\, Professor of Mathematics\, Duke University \nTitle: Molecular Pasta: Complex Entanglement in Biopolymers \nAbstract: If you’ve cooked spaghetti\, you’ve probably noticed how the pasta becomes entangled in the pot (especially in a small volume of water) or in your bowl afterwards.  This is a macro example of what I like to think about: entanglement in biopolymers.  Like linguine in a boiling pot of water\, our own DNA is a (group of) long skinny molecule(s) in the confined volume of an active\, energetic cell.  Unlike fettuccine though\, it’s life-or-death important to organize\, access and groom these long skinny DNA molecules.  So there’s a host of small machines (proteins) to do this\, in ways we’ve yet to fully understand.  Part of the complication is that we don’t yet have the precise experimental tools yet to watch (through microscopes) this dynamic process.  So instead we use the shape of these DNA molecules — before\, during and after their grooming — to back solve the precise processes that must be happening within the cell. \nIn this talk\, I’ll give an overview of some of these molecular biological questions\, why we care about them (as humans\, biologists and mathematicians) and some of my answers to these.  In particular I’ll highlight some more recent work on understanding DNA spatial graphs\, including those that look the the Greek letter theta\, and the exciting new mathematics we’ve developed to accurately model DNA during cell division \nBio: Dorothy Buck is an alumna of Pomona College\, and credits the Pomona Math department — including Professors Shahriar Shahriari\, Richard Elderkin and especially Erica Flapan — for igniting a love of both math and academia. Her 20+ years of research has worked to characterize entanglement – in circles\, linear segments and graphs – and to explore how biomolecular entanglement affects cellular structure and function. She investigates this molecular entanglement using a combination of topological (3-manifold) techniques and occasionally biochemical experiments. \nShe’s currently a professor at Duke\, after faculty positions in the US (Brown and Johns Hopkins) and the UK\, and much earlier an NSF postdoc and PhD with advisors in both Math and Molecular Biology.  After many years at the bench\, she now collaborates with experimental and computational experts.  She’s been the recipient of over $5M in grants\, which has funded both her own research and her large team\, as well as projects with architects and an Artist in Residence.

A tour of resolvent degree \nAbstract: Solving algebraic equations are among the oldest problems in mathematics. In this talk\, we offer a concrete\, visual\, and historical introduction to resolvent degree (RD)\, an invariant that aspires to quantify just how hard these problems are. The lineage of this theory includes the origins of topology\, Klein’s “hypergalois” program\, and centuries-old exploits in reducing numbers of coefficients\, which dare us to push beyond the solvable/unsolvable dichotomy. We will build towards the notion of versality central to Klein’s vision\, with a nod to our general framework implemented in joint work with Alexander Sutherland and Jesse Wolfson\, that permits us to address resolvent questions via classical invariant theory. We will conclude by reflecting on the past and future of resolvent problems\, along with what we do and don’t know about RD.

This theorem is fascinating because of its very simple hypotheses\, its surprisingly strong conclusion\, and its clever and elementary proof that uses not much more than the intermediate value theorem and some careful bookkeeping.

By considering the vector space spanned by links drawn on a surface and imposing these skein relations\, we obtain an algebra known as the Kauffman bracket skein algebra of the surface. These algebras have been studied by many authors\, including F. Bonahon and H. Wong\, and much is known about their structure. Replacing SL(2) by SL(3) or any other higher rank Lie group gives rise to a new skein algebra involving not only links but also certain graphs called webs. In this talk\, we will discuss some of the complications involved with studying skein algebras built from webs on surfaces and then present ways of getting around them. Some of this work is joint with F. Bonahon.

One example is Hilbert’s 13th Problem\, a conjecture going back long before Hilbert. Indeed\, the invention of algebraic topology grew out of an effort to understand how the roots of a polynomial depend on the coefficients. The goal of this talk is to explain part of the circle of ideas surrounding these questions. Along the way\, we will encounter some beautiful classical objects – the space of monic\, degree d square-free polynomials\, algebraic functions\, lines on cubic surfaces\, level structures on Jacobians\, braid groups\, Galois groups\, and configuration spaces – all intimately related to each other\, all with mysteries still to reveal. This is ongoing joint work with Benson Farb and Mark Kisin. \nBio: Jesse Wolfson is an associate professor and vice chair of inclusive excellence in the department of mathematics at the University of California\, Irvine.  His research focuses on long-standing open problems at the interface of algebra\, geometry and topology.  His perspective on geometry and topology emerges in part from his long-running exchange with choreographer Reggie Wilson. He currently serves on the board of directors of Wilson’s Fist and Heel Performance Group\, an internationally acclaimed Brooklyn based “Post-African neo-hoodoo modern dance company.” URL:https://colleges.claremont.edu/ccms/event/ccms-colloquium-braids-polynomials-and-hilberts-13th-problem-jesse-wolfson-uc-irvine/ CATEGORIES:Colloquium ORGANIZER;CN="Bahar Acu":MAILTO:Bahar_Acu@pitzer.edu END:VEVENT BEGIN:VEVENT DTSTART;TZID=America/Los_Angeles:20241029T150000 DTEND;TZID=America/Los_Angeles:20241029T160000 DTSTAMP:20241024T185135Z CREATED:20240928T044917Z LAST-MODIFIED:20241024T185135Z UID:10002167-1730214000-1730217600@colleges.claremont.edu SUMMARY:Claremont Topology Seminar: Orsola Capovilla-Searle (UC Davis) DESCRIPTION:We welcome all undergraduate/graduate students and faculty to attend topology seminar! \nSpeaker: Orsola Capovilla-Searle (UC Davis) \nTitle: Exact Lagrangian fillings of Legendrian links \nAbstract: An important problem in contact topology is to understand Legendrian submanifolds; these submanifolds are always tangent to the plane field given by the contact structure. Legendrian links arise as wavefronts in optics\, and can sometimes be used to distinguish contact structures. Legendrian links can also arise as the boundary of exact Lagrangian surfaces in the standard symplectic 4-ball which are called fillings of the link. In the last seven years\, our understanding of the moduli space of fillings for various families of Legendrians has greatly improved thanks to tools from sheaf theory\, Floer theory and cluster algebras. I will talk about recent work establishing connections between fillings and Newton polytopes\, as well as applications to higher dimensional Legendrian submanifolds and non-orientable fillings.

They all involve frameworks made of rigid parts attached at flexible joints and are designed to move with one degree of freedom. In 1981 architect Santiago Calatrava wrote a PhD thesis\, “Concerning the Foldability of Space Frames\,” containing a systematic exploration of the geometry and design of foldable frameworks. I’ll use his thesis as a jumping off point to explore the Geiringer-Laman Theorem and ideas for further research.\n \nBio:  Jessica Sidman loves to work on pure and applied problems at the intersection of computational algebra\, algebraic geometry\, and combinatorics. Her recent work in rigidity theory combines aspects of these three fields\, and all got started when an undergraduate doing a thesis on protein folding asked her a question about projective space. She got her B.A. from Scripps College\, a Ph.D. from the University of Michigan\, and did postdoctoral work at UC Berkeley and UMass Amherst.  She was the Professor of Mathematics on the John Stewart Kennedy Foundation at Mount Holyoke College and is now the Brian E. Boyle Professor in Mathematics and Computer Science at Amherst College.

However\, there is a tool useful for probing the edges of such fractals: tubular neighborhoods. In this talk\, we’ll introduce the theory of fractal tube formulae which describe the volumes of such tubular neighborhoods\, illustrating through our recent work on generalized fractal snowflakes. In the process\, we’ll touch on the theory of complex dimensions and tubular zeta functions that capture the (multiplicative) oscillations appearing in the geometry of fractals.
