Multiple L-values of conductor four, Entringer numbers, and modular forms

Lunedì 3 aprile 2023 alle ore 16:00 Masanobu Kaneko (Kyushu University) terrà un seminario di Teoria dei Numeri dal titolo "Multiple L-values of conductor four, Entringer numbers, and modular forms".

Abstract:  Multiple zeta values are multi-indexed generalizations of the values of the Riemann zeta function at positive integer arguments, and multiple L-values are further generalizations with Dirichlet characters. We study the multiple L-values
with characters of conductor four, and find an unexpected connection to the so-called Entringer numbers in combinatorics. Also discussed is a conjectural relation to period polynomials associated to modular forms of level four.
This is a joint work with Hirofumi Tsumura.

Il seminario avrà luogo in presenza presso il Dipartimento di Matematica e Fisica
