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. Joint work (in various combinations) with K. Aguilar\, A. Böttcher\, L. Bouthat\, Á. Chávez\, L. Fukshansky\, M. Mitkovski\, M. Omar\, C. O’Neill\, J. Volčič and students A. Chhabra\, J. Hurley\, G.

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. (Containing joint work with Ken Ono\, Hasan Saad and joint work with Ruofan Jiang)

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.

SUMMARY:Claremont Topology Seminar: Will Hoffer (UC Riverside)
DESCRIPTION:We welcome all undergraduate/graduate students and faculty to attend topology seminar! \nSpeaker: Will Hoffer (UC Riverside) \nTitle: Tube Formulae for Fractal Snowflakes \nAbstract: Fractals like the von Koch snowflake have rough boundaries\, often having nowhere defined tangent lines/spaces. 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.

SUMMARY:Frameworks in Motion: Design\, Theory\, and Fabrication (Jessica Sidman\, Amherst College
DESCRIPTION:Speaker: Jessica Sidman\, Professor of Mathematics and Computer Science\, Amherst College \nTitle: Frameworks in Motion: Design\, Theory\, and Fabrication \nAbstract: What do your umbrella\, a folding gate\, and a scissor lift have in common? 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.

SUMMARY:Sequences with identical autocorrelation spectra (Daniel Katz\, Cal State Northridge)
DESCRIPTION:In this talk\, we explore sequences and their autocorrelation functions. Knowing the autocorrelation function of a sequence is equivalent to knowing the magnitude of its Fourier transform.  Resolving the lack of phase information is called the phase problem.  We say that two sequences are equicorrelational to mean that they have the same aperiodic autocorrelation function.  We investigate the necessary and sufficient conditions for two sequences to be equicorrelational\, where\nwe take into consideration the alphabet from which their terms are drawn.  There are trivial forms of equicorrelationality arising from modifications that predictably preserve the autocorrelation\, for example\, negating the sequence or writing the sequence in reverse order and then complex conjugating every term.  By an exhaustive search of binary sequences up to length $44$\, we find that nontrivial equicorrelationality among binary sequences does occur\, but is rare.  We say that a positive integer $n$ is {\it unequivocal} to mean that there is no pair of nontrivially equicorrelational binary sequences of length $n$; otherwise $n$ is {\it equivocal}.  For integers $n \leq 44$\, we found that the unequivocal ones are $1$–$8$\, $10$\, $11$\, $13$\, $14$\, $19$\, $22$\, $23$\, $26$\, $29$\, $37$\, and $38$.  We prove that any multiple of a equivocal number is also equivocal\, and pose open questions as to whether there are finitely or infinitely many unequivocal numbers and whether the probability of nontrivial equicorrelationality occurring tends to zero as the sequence length tends to infinity.  (This is joint work with Adeebur Rahman and Michael J Ward.)

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.

SUMMARY:CCMS Colloquium: Braids\, Polynomials\, and Hilbert’s 13th Problem (Jesse Wolfson\, UC Irvine)
DESCRIPTION:Speaker:Jesse Wolfson\, UC Irvine \nTitle: Braids\, Polynomials\, and Hilbert’s 13th Problem \nAbstract: There are still completely open fundamental questions about polynomials in one variable. 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.”

SUMMARY:GEMS November 2nd Session
DESCRIPTION:This GEMS session will be facilitated by Professor David Bachman from Pitzer College. \nTitle: How does ChatGPT work? \nAbstract: In 2022 ChatGPT took the world by storm and challenged our ideas of what computers are capable of. However\, few people have any sense of how this technology works. Through hands-on activities participants will learn about neural networks (the engines that power language models like ChatGPT)\, and about how computers can generate text that reads like it was written by a human.

SUMMARY:Noether-Lefschetz theory and class groups (John Brevik\, Cal State Long Beach)
DESCRIPTION:The classical Noether-Lefschetz Theorem states that a suitably general algebraic surface S of degree d ≥ 4 in complex projective 3-space P3 contains no curves besides complete intersections\, that is\, curves of the form S ∩ T where T is another surface. After discussing briefly Noether’s non-proof of this theorem and hinting at the idea behind Lefschetz’s proof\, I will sketch some of our recent progress in generalizing this theorem and its implications for global and local divisor class groups. We explore the question of what class groups are possible for local rings on surfaces in a particular analytic isomorphism class and show the ubiquitousness of unique factorization domains among such rings. Joint work with Scott Nollet (Texas Christian University).

SUMMARY:Claremont Topology Seminar: Vijay Higgins (UCLA)
DESCRIPTION:We welcome all undergraduate/graduate students and faculty to attend topology seminar! \nSpeaker: Vijay Higgins (UCLA) \nTitle: Webs and skein algebras \nAbstract: The Jones polynomial of a link can be computed diagrammatically by using skein relations\, which encode the representation theory of SL(2). 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.

SUMMARY:CCMS Colloquium: Dynamical Systems and the Period 3 Implies Chaos Theorem (Michelle Manes\, AIM)
DESCRIPTION:Speaker: Michelle Manes\, AIM \nTitle: Dynamical Systems and the Period 3 Implies Chaos Theorem \nAbstract: Sharkovskii’s theorem\, sometimes called “period 3 implies chaos\,” concerns a one-dimensional real dynamical system: a function from the real line to itself that you iterate and study the orbits of points. 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. Like Sharkovskii’s theorem\, my mathematics research lives in the world of iterated dynamical systems\, and I’ll end by telling you a bit about some interesting number theoretic questions one can ask (and sometimes answer) in this context. \nBio: Michelle Manes received her AB in mathematics from UC Berkeley\, an MEd in Deaf Education from Boston University\, and an ScM and PhD in mathematics from Brown University. She was a professor in the mathematics department at the University of Hawaii for 15 years before leaving to join the American Institute of Mathematics (in Pasadena) as Deputy Director. She has also worked as a program officer at the National Science Foundation. She has taught mathematics at every level from 3rd grade through graduate school and has co-authored textbooks for middle grades mathematics\, high school geometry\, linear algebra\, and preservice elementary teachers. \nDr. Manes does research in number theory\, primarily in the field of arithmetic dynamics. She has authored over 30 articles\, most of them in collaboration with some of her best friends. She believes deeply in collaboration\, mentoring\, and professional service. She has served on committees for the Association for Women in Mathematics (AWM)\, the Mathematical Association of America (MAA)\, and the American Mathematical Society (AMS). She currently serves as the Associate Secretary for the Western Section of the AMS and as an editor-in-chief for La Matematica\, the flagship journal of the AWM. She has received numerous accolades including the Regents Medal for Excellence in Teaching at the University of Hawaii and the Haimo Award for Distinguished College or University Teaching of Mathematics from the MAA Golden Section and an AWM Service Award. She has been named a Fellow of the AWM and of the AMS.

SUMMARY:Traces of Partition Eisenstein series (Ken Ono\, University of Virginia)
DESCRIPTION:Integer partitions are ubiquitous in mathematics\, arising in subjects as disparate as algebraic combinatorics\, algebraic geometry\, number theory\, representation theory\, to mathematics physics. Many of the deepest results on partitions have their origin in the work of Ramanujan. In this lecture\, we will describe a completely new and unexpected role for partitions that also arises from the mysterious “lost notebook” of Ramanujan. We discover and explain the role of new q-series called “partition Eisenstein series”. These functions magically pop up as the key device for solving a conjecture of Andrews and Berndt\, for studying symmetric functions of 2-dimensional lattice sums\, for determining the properties of Andrews-Garvan “crank statistic”\, and for representing the Taylor coefficients of virtually every interesting Jacobi automorphic form. This talk will tell the story of the recent discovery of these functions\, and will offer a brief tour of these applications.

SUMMARY:Claremont Topology Seminar: Claudio Gomez-Gonzales (Carleton College - UC Irvine)
DESCRIPTION:We welcome all undergraduate/graduate students and faculty to attend the Topology Seminar! \nSpeaker: Claudio Gomez-Gonzales (Carleton College – UC Irvine) \nTitle: How hard could it be? 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 talk is designed to be accessible for undergraduates—let’s do some math!

SUMMARY:CCMS Colloquium: Molecular Pasta\, Complex Entanglement in Biopolymers (Dorothy Buck\, Duke Uni.)
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.
