Claremont Topology Seminar: Shane Rankin (University of California, Riverside)

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

We especially welcome all undergraduates and graduate students to attend topology seminar! Speaker: Shane Rankin (University of California, Riverside) Title: Symplectic Hodge Theory on Lie Algebroids Abstract: Symplectic Hodge Theory was developed in the late 80s to answer a conjecture of Brylinksi. Since then it has been used to understand the gap between Symplectic and […]

CCMS Colloquium: Journey of Black Mathematicians- Creating Pathways (Movie Screening, A film by George Csicsery)

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

Title: Journey of Black Mathematicians Film Description: Creating Pathways (2025) highlights the lives of Black mathematicians who pursued their education at predominantly White institutions. The film gauges the impacts of segregation and prejudice, surveys attitudes around identity, and introduces programs aimed at increasing the number of African Americans in STEM fields. Exploring questions about the […]

Applied Math Seminar: Ryan Aschoff (UC Riverside)

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

Title: Smooth non-decaying solutions to the 2D dissipative quasi-geostrophic equations Abstract: In this talk we explore the two-dimensional dissipative surface quasi-geostrophic (SQG) equation with fractional diffusion of order 2α for α ∈ (1/2,1], focusing on the setting where the initial data does not decay at spatial infinity and periodicity is not assumed. In geophysical applications, […]

Claremont Topology Seminar: Morgan Weiler (University of California, Riverside)

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

We especially welcome all undergraduates and graduate students to attend topology seminar! Speaker: Morgan Weiler (University of California, Riverside) Title: Anchored symplectic embeddings and 2-parameter persistence Abstract: Symplectic geometry is a generalization of classical mechanics, in which position and momentum coordinates are paired. In two dimensions, symplectic geometry is equivalent to volume-preserving geometry, but in […]

GEMS March 1st Session

Shanahan 1480, Harvey Mudd College 301 Platt Blvd., Claremont, CA, United States

This GEMS session will be facilitated by Professor Jemma Lorenat from Pitzer College. Title: Playing with the Rules of Geometries Abstract:  This session will explore how a small set of rules can be used to build and investigate geometrical objects. Through drawing, folding, and imagining, we will see how a limited number of possible actions ground a wide range […]

Enumerative Invariants from Derived Categories III (Reginald Anderson, CMC)

Estella 2113

We’ll first define the two-point gravitational correlators which appeared last week as descendant Gromov-Witten invariants. By request, we’ll then introduce Gromov-Witten invariants as they appear in the expository work https://arxiv.org/abs/2501.03232 and give CP^1 to demonstrate some of the identities which GW invariants satisfy. If time allows, we’ll also give the small and big quantum cohomology for CP^1.

Applied Math Seminar: Efstratios Tsoukanis (Claremont Graduate University)

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

Title: Bi-Lipschitz Invariants Abstract: Consider a finite-dimensional real vector space and a finite group acting unitarily on it. We investigate the general problem of constructing Euclidean stable embeddings of the quotient space of orbits. Our embedding relies on subsets of sorted coorbits with respect to chosen window vectors. Our main injectivity results examine the conditions […]

Claremont Topology Seminar: Carrie Frizzell (Scripps College)

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

We especially welcome all undergraduates and graduate students to attend topology seminar! Speaker: Carrie Frizzell (Scripps College) Title: A Primer on Tropical Geometry Abstract: Max-plus and min-plus semifields—coined tropical semifields—appeared in the 1970s in the work of the computer scientist Imre Simon. Since then, the field of tropical geometry has developed rapidly. In this talk, […]

No CCMS Colloquium!

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

N+12th Southern California Topology Colloquium

Benson Auditorium 1050 N Mills Ave., Claremont, CA, United States

The Claremont Topology Seminar, with funding from Pitzer College and the NSF, is pleased to sponsor the N+12th Southern California Topology Colloquium (SCTC). SCTC is a one-day conference primarily attended by mathematicians from the Southern California area. This year, the colloquium will be held at the Benson Auditorium at Pitzer College on Saturday, March 8th, […]
