  • 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 […]

  • 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 […]

  • 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 […]

  • Applied Math Seminar: Sarah Robinson (Claremont McKenna College)

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

    Title: Do Taxes Affect Pre-Tax Income Inequality? Evidence from 100 Years of U.S. States Abstract: We study how U.S. state taxes have affected pre-tax income inequality during the last century. Our primary analysis focuses on the top marginal personal income and corporate income tax, and their effect on top incomes and top income shares within […]

  • Claremont Topology Seminar: Iris Yoon (Wesleyan University)

    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: Iris Yoon (Wesleyan University) Title: Dowker duality, profunctors, and spectral sequences Abstract: I will present three short, new proofs of Dowker duality using various poset fiber lemmas. I will introduce modifications of joins and products of simplicial complexes called relational join and […]

  • CCMS Colloquium: (Iris Yoon, Wesleyan University)

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

    Speaker: Iris Yoon, Professor of Mathematics, Wesleyan University Title: How Topology Reveals Structure in Neuroscience Data Abstract: We live in an exciting time where new data is generated at an exponential rate. Such data explosion necessitates the development of novel methods for studying large, noisy, and complex data. One interesting aspect of data is its shape and […]
