The forbidden quiver of a link (Sam Nelson, CMC)
Virtual links can be represented as equivalence classes of Gauss diagrams under Reidemeister moves. The Forbidden Moves are moves which look plausible but change the virtual isotopy class of the […]

Sampling from the proper colorings of a graph using a number of colors linear in the maximum degree in expected linear time (Mark Huber, CMC)
Emmy Noether Room, Estella 1021, Pomona College, 610 N. College Ave., Claremont, CA, United StatesAbstract: A proper coloring of a graph is an assignment of colors from \( \{1, 2, \ldots, k\} \) to each node of a graph such that no two nodes […]

Relationships between skein algebras (Helen Wong, CMC)
Estella 2099We will examine the multiplicative structure of two skein algebras--- the usual Kauffman bracket skein algebra of a surface (generated by loops) and a generalization of it due to Roger-Yang […]

GEMS February 7th Session
Shanahan B450, Harvey Mudd College 301 Platt Blvd., Claremont, United StatesThis GEMS session will be facilitated by Professor Teal Witter from Claremont McKenna College. Title: Who Can Write Down the Bigger Number? Abstract: If you had fifteen seconds to write the largest distinct whole number possible on an index card, what would you write? While most would look to the physical world for inspiration—counting the […]

A BKM-type criterion for the 3D incompressible Euler equations (Mustafa Aydin, USC)
Emmy Noether Room, Estella 1021, Pomona College, 610 N. College Ave., Claremont, CA, United StatesAbstract: The three-dimensional incompressible Euler equations describe the motion of an ideal fluid, yet the mechanisms that govern the possible loss of regularity of smooth solutions remain only partially understood. […]

Analysis Seminar: Generalized Elmendorf’s Theorem in Context (Sofía Martínez Alberga, Bryn Mawr College)
Estella 2099, Pomona College 610 N. College Ave., Claremont, CA, United StatesAbstract: In general, the objective of algebraic topology is to classify spaces using some algebraic invariants or up to some notion of equivalence. In the area of equivariant homotopy theory, […]

Explainability and Analysis of Variance (Zijun Gao, USC)
Emmy Noether Room, Estella 1021, Pomona College, 610 N. College Ave., Claremont, CA, United StatesAbstract: Existing tools for explaining complex models and systems are associational rather than causal and do not provide mechanistic understanding. We propose a new notion called counterfactual explainability for causal […]

Summer of Math Discovery: Two research projects on combinatorial polytopes (Andrés R. Vindas Meléndez, HMC)
Estella 2099This is a talk in two parts covering two projects that the speaker mentored over the summer of 2025. The first project deals with the study of polytopes that arise […]

Analysis Seminar: Choquet simplices of groups and C*-algebras (Itamar Vigdorovich, UCSD)
Estella 2099, Pomona College 610 N. College Ave., Claremont, CA, United StatesAbstract: Let C be a compact convex set (in a locally convex topological vector space). By Choquet’s theorem, every point in C is the barycenter of a probability measure supported on the extreme points. When this representing measure is unique, C is called a simplex. Simplices arise naturally in various fields of mathematics: the space […]
