  • Adaptive Experimental Design using Shrinkage Estimators (Evan Rosenman, Claremont McKenna College)

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

    In multi-armed trials, adaptive designs are a popular way to increase estimation efficiency or identify optimal treatments. Many recent papers have proposed adaptive methods for minimizing the error of unbiased estimators that consider each treatment arm in isolation. This approach may be inefficient, because it fails to borrow shared information across the treatment arms. We […]

  • Kloosterman sums and Bessel functions (Robert Cass, CMC)

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

    Kloosterman sums are explicit exponential sums which occur in several contexts in number theory and arithmetic geometry. Bessel functions encode a great deal of representation-theoretic information about finite groups of Lie type, but they are difficult to compute in general. In this talk, we will carefully define these objects and describe a direct relationship between […]

  • Edge Ideals via Independence Polynomials of Graphs — Dalena Vien (Bryn Mawr)

    Burkle 16, Claremont Graduate University 1021 N. Dartmouth Ave., Claremont, CA, United States

    Abstract: Edge ideals of graphs provide a fertile ground for uncovering combinatorial expressions for algebraic invariants of squarefree monomial ideals. Many algebraic invariants of these edge ideals directly reflect combinatorial properties […]

  • Number Theory meets Differential Equations: Using Homotopy Continuation to Compute Shabat Polynomials

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

    A Belyĭ pair \bigl( S,\, z(w) \bigr) is a compact, connected Riemann surface S together with a rational function z \colon S \to \mathbb{P}^1(\mathbb{C}) which has at most three critical values \bigl\{ 0,\, 1,\, \infty \bigr\}. The preimage z^{-1}\bigl( \bigr) \subseteq S \hookrightarrow \mathbb{R}^3 is a bipartite graph called a Dessin d'Enfant. When S = \mathbb{P}^1(\mathbb{C}) […]

  • Hilbert basis for conical semigroups and indecomposable elements (Lenny Fukshansky, CMC)

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

    The unique minimal generating set for a semigroup of lattice points in an n-dimensional polyhedral cone is called its Hilbert basis. In the case when the cone is spanned by lattice points, this Hilbert basis is finite, however its cardinality can be much larger than n. Nevertheless, a conjecture of Sebö states that each point […]

  • Claremont Topology Seminar: Sam Nelson (CMC)

    Speaker: Sam Nelson (CMC) Title: Permutation Jones Polynomials Abstract: The Jones Polynomial is an important invariant of knots with applications in physics, quantum computation and more. In this talk I will introduce a family of generalizations of the Jones polynomial associated to permutations of finite sets and discuss their properties. _______ We especially welcome all […]
