• Categorification of biquandle arrow weight invariants via quivers (Migiwa Sakurai, Shibaura Institute of Technology)

    Estella 2099

    Biquandle arrow weights invariants are enhancements of the biquandle counting invariant for oriented virtual and classical knots defined from biquandle-colored Gauss diagrams using a tensor over an abelian group satisfying certain properties. In this talk, we categorify the biquandle arrow weight polynomial invariant using biquandle coloring quivers, obtaining new infinite families of polynomial invariants of […]

  • CCMS Colloquium: Morse theory, Floer homology, and string topology (Ko Honda, UCLA)

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

    CCMS Colloquium invites you to a talk by Professor Ko Honda, Professor of Mathematics at UCLA. Title: Morse theory, Floer homology, and string topology Abstract: One of the most important theories in geometry/topology is Floer homology, which can be viewed as a Morse theory of a loop space of a manifold (a generalization of a surface to […]

  • LA City Council Reform: A Statistical Study of Alternatives (Evan Rosenman & Sarah Cannon, Claremont McKenna College)

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

    Abstract: The 2022 Los Angeles City Council scandal intensified public demand for governance reform, leading to the creation of the Los Angeles Charter Reform Commission. The commission is now considering proposals from civic and academic groups. Major recommendations include: eliminating the automatic election of candidates who win a primary majority, expanding the size of the […]

  • NO CCMS Colloquium this Friday!

    We'll be back next week!

  • CCMS Colloquium: Robert Cass (CMC)

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

    CCMS Colloquium invites you to a talk by Assistant Professor of Mathematics Robert Cass of Claremont McKenna College: Title: An introduction to the Langlands program Abstract: Class field theory, which was established in the early 20th century, has its origins in Gauss's law of quadratic reciprocity. As such, it allows one to determine whether certain […]

  • Bounds and Extremal Examples for the Hot Spots Ratio (Alex Hsu, University of Washington)

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

    Abstract: The shape of the fluctuations as heat approaches equilibrium in an insulated body are governed by the first Neumann eigenfunction of the Laplacian. Rauch's hot spots conjecture states that the extrema of the first nontrivial Neumann Laplacian eigenfunction for a Lipschitz domain lies on the boundary. While this conjecture is false in general, its […]

  • Analysis seminar: Transfinite Apollonian metric (Zair Ibragimov, CSU Fullerton)

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

    Title: Transfinite Apollonian metric Abstract: The concept of transfinite diameter of compact sets in the complex plane was introduced by Fekete in 1923. It is a generalization of the standard diameter of sets and has found many applications in the study of conformal mappings. The Apollonian metric was introduced by A. Beardon in 1995 and […]
