Wadim Zudilin: Irrationality through an irrational time (NTWS 023)
Channel: Number Theory Web Seminar
Date: 2023-05-28

Abstract: After reviewing some recent development and achievements related to diophantine problems of the values of Riemann's zeta function and generalized polylogarithms (not all coming from myself!), I will move the focus to \pi=3.1415926... and its rational approximations. Specifically, I will discuss a construction of rational approximations to the number that leads to the record irrationality measure of \pi. The talk is based on joint work with Doron Zeilberger.
