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 attribution that is motivated by the concept of genetic heritability in twin studies. Counterfactual explainability extends methods for global sensitivity analysis (including the functional analysis […]

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 from the convex hulls of stack-sorting on particular permutations. The second project deals with the study of symmetric edge polytopes of a finite simple graph, […]

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 […]

CCMS Colloquium: Mary Lou Zeeman (Bowdoin College)
Davidson Lecture Hall, CMC 340 E 9th St, Claremont, CA, United StatesCCMS Colloquium invites you to a talk by Mary Lou Zeeman (Bowdoin College) Title: A new framework for studying transient reactivity in two-dimensional systems. Abstract: Even if a linear system of ordinary differential equations (ODEs) has a globally attracting equilibrium, solutions of the ODEs may grow arbitrarily large in the short-term before returning to the equilibrium […]

CCMS Colloquium: Harrison Li (HMC)
Davidson Lecture Hall, CMC 340 E 9th St, Claremont, CA, United StatesCCMS Colloquium invites you to a talk by Harrison Li (HMC) Title: Precise analysis of blocked randomized experiments Abstract: I recently finished a multi-year project with collaborators analyzing a blocked randomized experiment to evaluate the effectiveness of a government job training program for unemployment insurance (UI) recipients in Rhode Island. In presenting the results, I will focus […]

Structure-Preserving Discretizations for Fokker–Planck Equations via the Energy Dissipation Law (Satish Chandran, UCR)
Emmy Noether Room, Estella 1021, Pomona College, 610 N. College Ave., Claremont, CA, United StatesAbstract: We present a new approach for deriving structure-preserving numerical discretizations of Fokker-Planck equations by establishing a connection between the Fokker-Planck equation and its semi-discrete master equation at the level of the energy-dissipation law. We determine the transition rate in the master equation via the detailed balance condition and the spatial discretization of the continuous […]

CCMS Colloquium: Lihong Zhao (Kennesaw State University)
Davidson Lecture Hall, CMC 340 E 9th St, Claremont, CA, United StatesCCMS Colloquium invites you to a talk by Lihong Zhao (Kennesaw State University) Title: Capturing heterogeneity in malaria transmission: an age-structured model with immune feedback and seasonality Abstract: Malaria remains a major global health burden, causing more than 600,000 deaths and over 249 million cases globally each year. Heterogeneity in malaria transmission is a critical factor that […]

GEMS March 7th Session
Shanahan 1480, Harvey Mudd College 301 Platt Blvd., Claremont, CA, United StatesThis GEMS session will be facilitated by Robbie Tran from Claremont Graduate University. Title: Formulating Equations as a Medium for Digital Art and Design Abstract: As we can utilize letters and words to write out mathematics (e.g. 2+2=4 can be written as “two plus two is equal to four”), this session seeks to explore the […]

An Odd Estimator for Shapley Values (Teal Witter, CMC)
Emmy Noether Room, Estella 1021, Pomona College, 610 N. College Ave., Claremont, CA, United StatesAbstract: The Shapley value is a ubiquitous framework for attribution in machine learning, encompassing feature importance, data valuation, and causal inference. However, its exact computation is generally intractable, necessitating efficient approximation methods. While the most effective and popular estimators leverage the paired sampling heuristic to reduce estimation error, the theoretical mechanism driving this improvement has […]

Hecke algebras and motives (Robert Cass, CMC)
Estella 2099Hecke algebras play a central role in both number theory and representation theory. While some Hecke algebras have explicit descriptions in terms of generators and relations, others are understood through structure constants that encode multiplicities in tensor products of representations. In this talk, I will discuss several projects with Thibaud van den Hove and Jakob […]
