Extremal problems for multiplicative functions
Time and place: Wednesday, November 6 at 16:15. Over Zoom and in colloquium watch events at mathematics departments (see bottom of page)
Speaker: Andrew Granville, Université de Montréal
Chaired by: Kaisa Matomäki, University of Turku
Title: Extremal problems for multiplicative functions
Abstract:
Nowadays there are two prominent approaches to questions about the distribution of prime numbers: Riemann's classical methods using zeros of zeta functions, and the recent pretentious theory of multiplicative functions (which is mostly a combination of older "ad hoc" techniques). In this talk we present the basics of this newer theory, how it relates closely to the theory of integral-delay equations and then focus on some recent work on extremal problems (in joint work of the speaker with Kevin Church, Kaisa Matomaki, Kannan Soundararajan and Daodao Yang).
Andrew Granville is Professor of Mathematics at Université de Montréal and a world-leading expert in analytic number theory. He has published several very influencial papers and is probably best known for developing, together with K. Soundararajan, the "pretentious" approach to number theory.
