A polyhedral view of refined q-t Catalan numbers (Max Hlavacek, Pomona College)

Argue Auditorium, Pomona College 610 N. College Ave., Claremont, CA, United States

Title: A polyhedral view of refined q-t Catalan numbers Speaker: Max Hlavacek Assistant Professor of Mathematics and Statistics department, Pomona College, Claremont Abstract: Many problems in algebraic combinatorics have geometric objects lurking in the background, and bringing these objects forward can shed some light on the original problem.  We begin with an introduction to polyhedral cones and their […]

Applied Math Seminar: Sarah Marzen (Department of Natural Science)

Emmy Noether Room, Estella 1021, Pomona College, 610 N. College Ave., Claremont, CA, United States

Title: How well do neurons, humans, and artificial neural networks predict? Abstract: 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 […]

Adinkras as Origami? (Edray Goins, Pomona College)

Estella 2113

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 […]

Claremont Topology Seminar: Reginald Anderson (CMC)

Estella 2099

We welcome all undergraduate/graduate students and faculty to attend topology seminar! Speaker: Reginald Anderson (CMC) Title: Presentations of derived categories Abstract: 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 […]

Analysis seminar: Stephan Ramon Garcia (Pomona College)

Estella 2131, Pomona College 610 N College Ave, Claremont, United States

Title: What can chicken McNuggets tell us about symmetric functions, positive polynomials, random norms, and AF algebras? Abstract: 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 […]

GEMS October 5th Session

Harvey Mudd College at the Shanahan Teaching and Learning Center 301 Platt Blvd., Claremont, CA, United States

Title:  How to use coins to make a 7-sided die Abstract:  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 […]

Counting matrix points via lattice zeta functions (Yifeng Huang, USC)

Estella 2113

​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.)​. The first problem is to count finite-field points on so called "varieties of matrix points''. They are created from […]

What Happens when Our Perspectives Don’t Align with the Math? (Anne Cawley, Cal Poly Pomona)

Argue Auditorium, Pomona College 610 N. College Ave., Claremont, CA, United States

Speaker: Anne Cawley, Associate Professor of Mathematics and Statistics, Cal Poly Pomona, CA Title: What Happens When Our Perspectives Don’t Align with the Math? Abstract: 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. […]

Analysis Seminar: Domains of Quantum Metrics on AF algebras (Katrine von Bornemann Hjelmborg, University of Southern Denmark (SDU))

Estella 2131, Pomona College 610 N College Ave, Claremont, United States

Title: Domains of Quantum Metrics on AF algebras Abstract: 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 […]

CCMS Colloquium: “Paths in Mathematics After Undergrad” Panel

CCMS Colloquium: “Paths in Mathematics After Undergrad” Panel We will be holding a virtual panel on careers and grad school after a bachelor’s mathematics degree, with a follow-up discussion time in breakout rooms. Panelists Brianna Huynh (PO-2024), MS student in MathEd at Cal Poly Pomona Taylor McAdam (HMC-2013), Visiting Assistant Professor of Mathematics, at Pomona […]
