Applied Math Seminar: Adolfo Rumbos (Pomona College)

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

Title: Existence and multiplicity of solutions for a cooperative elliptic system using Morse theory This is joint work with Leandro Recova (Cal Poly Pomona) Abstract

Claremont Topology Seminar: Song Yu (Caltech)

Estella 2099

We welcome all undergraduates and graduate students to attend topology seminar! Speaker: Song Yu (California Institute of Technology and Tsinghua Yau Mathematical Sciences Center) also a Pomona alum! Title: Knot invariants, Gromov-Witten invariants, and integrality conjectures Abstract: In this talk, we will take a peek at large N duality which is a deep correspondence between invariants […]

Math as Art and Recreation (Peter Kagey, HMC)

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

Title: Math as Art and Recreation Speaker: Peter Kagey, HMC Abstract: Recreational Mathematics is an area of math which is rooted in exploration and playfulness, and includes puzzles, games, art, and more. This talk takes a closer look at these ideas, emphasizing how a foundation of curiosity and play can lead to insightful connections with various […]

Shrinkage Estimation for Causal Inference and Experimental Design (Evan T. R. Rosenman)

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

Title: Shrinkage Estimation for Causal Inference and Experimental Design Speaker: Evan T. R. Rosenman, Assistant Professor of Statistics, Claremont McKenna College Abstract: Passive collection of observational data -- in settings such as medicine, insurance, and e-commerce -- is a ubiquitous feature of modern life. For statisticians, these ever-proliferating datasets are both promising and perilous. Observational […]

GEMS February 10th Session

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

Dagan Karp (Harvey Mudd College)

Estella 1021 (Emmy Noether Room), Pomona College Claremont, CA, United States

Title: Tropical Linear Series Abstract: In this talk I'll attempt to give a friendly and example-driven introduction to the theory of linear series on tropical curves. While in some respects mirroring the classical study of linear series, in the tropical setting there are many surprises and even basic questions remain open. This work is joint with […]

Quiver categorification of quandle invariants (Sam Nelson, CMC)

Estella 2099

Quiver structures are naturally associated to subsets of the endomorphism sets of quandles and other knot-coloring structures, providing a natural form of categorification of homset invariants and their enhancements. In this talk we will survey recent work in this area.

Claremont Topology Seminar: Luya Wang (Stanford)

Estella 2099

We welcome all undergraduates and graduate students to attend topology seminar! Speaker: Luya Wang (Stanford) Title: Deformation inequivalent symplectic structures and Donaldson's four-six question Abstract: Studying symplectic structures up to deformation equivalences is a fundamental question in symplectic geometry. Donaldson asked: given two homeomorphic closed symplectic four-manifolds, are they diffeomorphic if and only if their […]

Mirror Symmetry and Zeta Values (Sheel Ganatra, USC)

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

Title: Mirror Symmetry and Zeta Values Speaker: Sheel Ganatra, University of Southern California Abstract: Mirror symmetry is a conjectural correspondence, born out of ideas in string theory, between two geometries of very different nature. In its earliest mathematical appearance, mirror symmetry was used to make predictions for certain numerical measurements of one space in terms of […]

Cristian Lopez Morales (UNAL)

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

Join us for the first talk in the joint seminar with CCMS Applied Math and the Universidad Nacional de Colombia Title Serre Conjecture. Geometric interpretation of the Quillen-Suslin Theorem. Abstract: The Quillen-Suslin theorem asserts that over the polynomial ring with coefficients in a field K, every projective module is free. Despite the algebraic nature of […]

Point-counting and topology of algebraic varieties (Siddarth Kannan, UCLA)

Estella 2099

A projective algebraic variety X is the zero locus of a collection of homogeneous polynomials, in projective space. When the polynomials have integer coefficients, we can think of the k-valued points X(k) of the variety, for any field k. Now suppose we have two different fields k and k'. How does the behavior of X(k) […]

Claremont Topology Seminar: Puttipong Pongtanapaisan (Arizona State university)

Estella 2099

We welcome all undergraduates and graduate students to attend topology seminar! Speaker: Puttipong Pongtanapaisan (Arizona State University) Title: Building Knotted Objects Efficiently Abstract: Knotted objects can be constructed by gluing together standard pieces called handles. Understanding the minimum number of handles required for construction and their sequential attachment provides valuable insights into the complexity of entanglement. […]
