Mahler measures and L-functions

Wadim Zudilin (The University of Newcastle)

Abstract

The talk outlines a method for reducing the values of L-functions to periods, in particular, to Mahler measures of polynomials in two variables. Based on joint work with Mat Rogers and related work by Anton Mellit and François Brunault.
