• ANTC talk by Dagan Karp (HMC)

    Emmy Noether Room, Millikan 1021, Pomona College 610 N. College Ave., Claremont, California
  • Region colorings in knot theory (Sam Nelson, CMC)

    On Zoom

    In this talk we will survey recent developments in the use of ternary algebraic structures known as Niebrzydowski Tribrackets in defining invariants of knots, with some perhaps surprising applications.

  • Critical points of toroidal Belyi maps (Edray Goins, Pomona)

    On Zoom

    A Belyi map $\beta: \mathbb{P}^1(\mathbb{C}) \to \mathbb{P}^1(\mathbb{C})$ is a rational function with at most three critical values; we may assume these values are $\{ 0, \, 1, \, \infty \}$.  Replacing $\mathbb{P}^1$ with an elliptic curve $E: \ y^2 = x^3 + A \, x + B$, there is a similar definition of a Belyi […]

  • New norms on matrices induced by polynomials (Angel Chavez, Pomona)

    On Zoom

    The complete homogeneous symmetric (CHS) polynomials can be used to define a  family of norms on Hermitian matrices. These 'CHS norms' are peculiar in the sense that they depend only on the eigenvalues of a matrix and not its singular values (as opposed to the Ky-Fan and Schatten norms). We will first give a general overview behind […]

  • Damerell’s theorem: p-adic version, supersingular case (Pavel Guerzhoy, University of Hawaii)

    On Zoom

    It is widely believed that Weierstrass ignored Eisenstein's theory of elliptic functions and developed an alternative treatment, which is now standard, because of a convergence issue. In particular, the Eisenstein series of weight two does not converge absolutely while Eisenstein's theory assigned a value to this series. It is now well-known that the quantity which […]

  • Counting points in discrete subgroups (Jeff Vaaler, UT Austin)

    On Zoom

    We consider the problem of comparing the number of discrete points that belong to a set with the measure (or volume) of the set, under circumstances where we expect these two numbers to be approximately equal. We start with a locally compact, abelian, topological group G. We assume that G has a countably infinite, torsion […]
