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:Frobenius coin-exchange generating functions (Matthias Beck\, San Francisco State University)
DESCRIPTION:We study variants of the Frobenius coin-exchange problem: Given n positive relatively prime parameters\, what is the largest integer that cannot be represented as a nonnegative integral linear combination of the given integers? This problem and its siblings can be understood through generating functions with 0/1 coefficients according to whether or not an integer is representable. In the 2-parameter case\, this generating function has an elegant closed form\, from which many corollaries follow\, including a formula for the Frobenius problem. We establish a similar closed form for the generating function indicating all integers with exactly k representations\, with similar wide-ranging corollaries. This is joint work with Leonardo Bardomero.

SUMMARY:Claremont Topology Seminar: Hyunki Min (UCLA)
DESCRIPTION:Title: Contact structures and the mapping class group of lens spaces \nAbstract: One important problem in contact topology is to classify contact structures on a given manifold. Around 20 years ago\, Giroux and Honda classified contact structures on lens spaces. A natural question to ask after that is how the transformations on lens spaces interact with the contact structures. In this talk\, we study contactomorphisms on lens spaces\, which are diffeomorphisms preserving the contact structure. We show that the contact mapping class group of a standard contact lens space is a subgroup of the mapping class group of the lens space.

SUMMARY:Lonely Runners and My Favorite Polyhedron (Matthias Beck\, San Francisco State University)
DESCRIPTION:Title: Lonely Runners and My Favorite Polyhedron \nSpeaker: Matthias Beck\, Department of Mathematics\, San Francisco State University \nAbstract: We study the Lonely Runner Conjecture\, conceived by Wills in the 1960’s\, and originally phrased in terms of Diophantine approximation: Given positive integers n_1\, n_2\, …\, n_k\, there exists a positive real number t such that for all 1 ≤ j ≤ k the distance of t n_j to the nearest integer is at least 1/(k+1). This conjecture can be recast in lay terms: if k runners with different (constant) speeds move around a circular track of length 1\, then for each runner there will be a time when they have distance at least 1/k to the others. This (in)famous conjecture in combinatorial number theory is open for k ≥ 7.We will give a brief history of the Lonely Runner Conjecture and some of its variants\, emphasizing a view-obstruction approach by Cusick and recent work by Henze and Malikiosis; our goal is to promote a polyhedral ansatz to the Lonely Runner Conjecture. Our results include affirmative instances that become (quite literally) visible through polyhedral geometry. \nBased on joint work with Serkan Hosten (SF State) and Matthias Schymura (Rostock). \n\n\n\n\n\nMatthias Beck is a professor of mathematics at San Francisco State University and has had visiting positions at SUNY Binghamton\, the Mathematical Sciences Research Institute in Berkeley\, the Max-Planck-Institute in Bonn\, Cornell University\, Vassar College\, and the Freie Universität in Berlin. Matt’s research is in combinatorics and number theory\, in particular\, counting integer points in polyhedra and the application of these enumeration functions to various mathematical topics and problems. He (co-)authored four books and numerous research papers\, many of which feature student coauthors. Matt was honored with the Mathematical Association of America’s Haimo Award for Distinguished College or University Teaching of Mathematics in 2013.x`

SUMMARY:Applied Math Seminar: Adam Yassine (Pomona College)
DESCRIPTION:Title: On the Composition of Classical Mechanical Systems \nAbstract: Compositionality is a basic principle for understanding the physical world. The underlying idea is to study a system by studying the ways in which the components of the system compose to form the system. Category theory is an area in mathematics that is particularly well-suited for studying questions about compositionality. This talk will outline a way to use category theory to study classical mechanical systems from a compositional perspective.

SUMMARY:History and Philosophy of Mathematics Seminar: Kris Palmieri (University of Chicago)
DESCRIPTION:True Grit: Writing the History of Women at Yerkes Observatory\, 1895–1950 \nAbstract: \nWomen at Yerkes Observatory earned advanced degrees\, conducted their own research\, collaborated on projects with peers of both sexes\, and authored publications in their own names in the first half of the Twentieth Century. Yet Alice Hall Farnsworth\, Mary Murray Hopkins\, Harriet McWilliams Parsons\, and Evelyn Worhnam Wickham – to name only a few – are unknown even amongst specialists. This is in large part because their lives and their labor are all but invisible in published sources and public records. Yet the voices of these women remain preserved in archives across the country – and this presents us with an unparalleled opportunity to reconstruct their lived experiences as women in science. \nThis paper explores the ways in which biography provides a uniquely productive lens for reconstructing the history of women at Yerkes. In so doing\, however\, it also explores the limits of biography for a research project that is anchored by its focus on a specific institutional space and asks how these limits might be overcome.

SUMMARY:f^*-vectors of lattice polytopes (Max Hlavacek\, Pomona College)
DESCRIPTION:The Ehrhart polynomial of a lattice polytope P counts the number of integer points in the nth integral dilate of P. The f^* -vector of P\, introduced by Felix Breuer in 2012\, is the vector of coefficients of the Ehrhart polynomial with respect to the binomial coefficient basis . Similarly to h and h^* -vectors\, the f^* -vector of P coincides with the f-vector (counting faces of every dimension) of its unimodular triangulations (if they exist). We give several inequalities that hold among the coefficients of f^*-vectors of polytopes. These inequalities resemble striking similarities with existing inequalities for the coefficients of f-vectors of simplicial polytopes. Even though f^* -vectors of polytopes are not always unimodal\, we describe several families of polytopes that carry the unimodality property.

SUMMARY:Adinkra Heights and Color-Splitting Rainbows (Ursula Whitcher\, American Mathematical Society)
DESCRIPTION:Title: Adinkra Heights and Color-Splitting Rainbows \nSpeaker: Ursula Whitcher\, American Mathematical Society \nAbstract: Adinkras are decorated graphs that encapsulate information about conjectural relationships between fundamental particles in physics. If we color the edges of an Adinkra with a rainbow of shades in a specific order\, we obtain a special curve that we can study usingalgebraic and geometric techniques. We use this structure to characterize height functions on Adinkras\, then show how to compute the same information using data from our rainbow. This talk describes joint work with Amanda Francis. \n\n\n\n\n\nDr. Ursula Whitcher is an associate editor at Math Reviews (MathSciNet)\, a project of the American Mathematical Society\, covering a range of areas from algebraic geometry to history of mathematics. Before joining the AMS\, Dr. Whitcher earned a PhD from the University of Washington\, was a Teaching and Research Postdoctoral Fellow at Harvey Mudd\, and became an associate professor at the University of Wisconsin-Eau Claire. Find Dr. Whitcher’s mathematically inspired poetry and fiction in Asimov’s Science Fiction Magazine\, Analog\, or the Journal of Humanistic Mathematics.

SUMMARY:Continued fractions\, directed graphs\, and defining spectral triples on Effros-Shen AF algebras (Samantha Brooker\, Arizona State University)
DESCRIPTION:The Effros-Shen algebra corresponding to an irrational number $\theta$ can be described by an inductive sequence of direct sums of matrix algebras\, where the continued fraction expansion of $\theta$ encodes the dimensions of the summands\, and how the matrix algebras at the nth level fit into the summands at the (n+1)th level. In recent work\, Mitscher and Spielberg present an Effros-Shen algebra as the C*-algebra of a category of paths – a generalization of a directed graph – determined by the continued fraction expansion of \theta. With this approach\, the algebra is realized as the inductive limit of a sequence of infinite-dimensional\, rather than finite-dimensional\, subalgebras. Drawing on a construction by Christensen and Ivan\, we use this inductive limit structure to define a spectral triple\, trading the advantages of working with finite-dimensional approximants for the techniques provided by the category of paths\, pursuant to studying the algebras as quantum compact metric spaces. I will discuss categories of paths and their precursors\, graph C*-algebras\, the example of Mitscher and Spielberg\, and a bit about the spectral triple construction. This is joint work with Konrad Aguilar and Jack Spielberg.

SUMMARY:On the Cox ring of a weighted projective plane blown-up at a point (Javier Gonzalez Anaya\, HMC)
DESCRIPTION:The Cox ring of a projective variety is the ring of all its meromorphic functions\, together with a grading of geometric origin. Determining whether this ring is finitely generated is a challenging task\, even for simple examples. In this talk\, we will discuss our efforts to tackle this problem for a specific class of varieties\, known as blow-ups of weighted projective planes (WPP). Through the lens of toric geometry\, a WPP is characterized by a rational plane triangle. This allows us to reinterpret the problem combinatorially and show that the solution often emerges from a parameter space of such triangles. This is joint work with José Luis González and Kalle Karu.

SUMMARY:What can chicken nuggets tell us about symmetric functions\, positive polynomials\, random norms\, and AF algebras? (Stephan Garcia\, Pomona)
DESCRIPTION:A simple question about chicken nuggets connects everything from analysis and combinatorics to probability theory and computer-aided design.  With tools from complex\, harmonic\, and functional analysis\, probability theory\, algebraic combinatorics\, and spline theory\, we answer many 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.

SUMMARY:Claremont Topology Seminar: Melody Molander (UCSB)
DESCRIPTION:Title: Skein Theory of Affine ADE Subfactor Planar Algebras \nAbstract: Subfactor planar algebras first were constructed by Vaughan Jones as a diagrammatic axiomatization of the standard invariant of a subfactor. These planar algebras also encode two other invariants of the subfactors: the index and the principal graph. The Kuperberg Program asks to find all diagrammatic presentations of subfactor planar algebras. This program has been completed for index less than 4. In this talk\, I will introduce subfactor planar algebras and give some presentations of subfactor planar algebras of index 4 which have affine ADE Dynkin diagrams as their principal graphs.

SUMMARY:“The science of Mathematics is not crystallized into text-books” : The Bryn Mawr Mathematical Journal Club (1896 — 1924)\, (Jemma Lorenat\, Pitzer College)
DESCRIPTION:Title: “The science of Mathematics is not crystallized into text-books” : The Bryn Mawr Mathematical Journal Club (1896 — 1924) \nSpeaker: Jemma Lorenat\, Pitzer College \nAbstract: As mathematics departments in the United States began to shift toward standards of original research at the end of the nineteenth century\, many adopted journal clubs as forums for students to synthesize and share new research. The Bryn Mawr Mathematical Journal Club\, maintained episodically between 1896 and 1924\, began as a supplement to the graduate course offerings. Each semester student and professor participants focused on a single disciplinary area or surveyed what had been published lately. The Notebooks containing these reports were stored on the open shelves of the college library. These collectively composed documents record ways in which graduate students transcribed and interpreted contemporary mathematics. This talk focuses on the entries of Virginia Ragsdale\, in which she formulated research questions\, tested potential strategies\, and pursued novel results in topology. \n\n\n\n\n\nJemma Lorenat is a historian of mathematics at Pitzer College. She enjoys learning about the long nineteenth century\, visualization\, quantification\, ordinary people becoming mathematicians\, food\, and many other things. Her forthcoming book is about how the local environment of Bryn Mawr College shaped mathematical practices there.
