  • Some Diophantine analogies between Dirichlet series and polynomials (Vesselin Dimitrov, Caltech)

    Estella 2113

    I will present an integral — requiring no character twists — converse theorem for recognizing when is a Dirichlet series with algebraic integer coefficients equal to the L-function of a modular form. This refines the unbounded denominators conjecture of Atkin and Swinnerton-Dyer. Analogies with basic function field arithmetic then suggest a quantitative refinement which precludes a pair of GL(2) automorphic L-functions […]

  • Permutation pattern avoidance, alternating sign matrices, and asymptotics (Justin Troyka, Cal State LA)

    Estella 2113

    A big area in combinatorics over the last several decades has been the study of pattern-avoiding permutations, whose enumeration is exciting and mysterious. Alternating sign matrices (ASMs) are a generalization of permutations whose study in combinatorics has also been exciting and mysterious. In this talk, I will explain some new asymptotic results involving the number […]

  • The ANTC of ChatGPT: On the Mathematical Foundations of Large Language Models (Gizem Karaali, Pomona)

    Estella 2113

    Large Language Models like ChatGPT rely on surprisingly familiar mathematics. This talk will explore how ideas from (linear) algebra, number theory and combinatorics  appear — both directly and indirectly — in the structure and behavior of these models. Along the way, we’ll touch on themes like structure, symmetry, and scale, and consider how abstract mathematical […]
