• The forbidden quiver of a link (Sam Nelson, CMC)

    Estella 2099

    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 […]

  • CCMS Colloquium: John Baez (UCR)

    Davidson Lecture Hall, CMC 340 E 9th St, Claremont, CA, United States

    CCMS Colloquium invites you to a talk by John Baez (UCR) Title: The mathematics of tuning systems Abstract: Leibniz said "Music is the pleasure the human mind experiences from counting without being aware that it is counting."  The first step is choosing a tuning system — the frequency ratios between pitches in a scale.  Different kinds […]

  • Relationships between skein algebras (Helen Wong, CMC)

    Estella 2099

    We 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 […]

    CCMS Colloquium invites you to a talk by Teal Witter (CMC) Title: Exactly Computing do-Shapley Values Abstract:  Causal questions lie at the heart of scientific inquiry, from evaluating economic policies […]

  • GEMS February 7th Session

    Shanahan B450, Harvey Mudd College 301 Platt Blvd., Claremont, United States

    This 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 […]

  • 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 States

    Abstract: 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 States

    Abstract: 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, the goal is the same but now spaces equipped with a group action are considered and algebraic invariants of choice are homotopy groups. It turns […]

  • CCMS Colloquium: Sofia Martinez Alberga (Bryn Mawr College)

    Davidson Lecture Hall, CMC 340 E 9th St, Claremont, CA, United States

    CCMS Colloquium invites you to a talk by Sofia Martinez Alberga (Bryn Mawr College) Title: Stay in the Loop and Fun Group Abstract: In this talk, we will discuss the goal of […]

  • Explainability and Analysis of Variance (Zijun Gao, USC)

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

    Abstract: 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 […]

  • Analysis Seminar: Choquet simplices of groups and C*-algebras (Itamar Vigdorovich, UCSD)

    Estella 2099, Pomona College 610 N. College Ave., Claremont, CA, United States

    Abstract: 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 […]
