The Riemann zeta function in short intervals [after Najnudel, and Arguin, Belius, Bourgade, Radziwiłł, and Soundararajan]

Abstract: This is the text to accompany my Bourbaki seminar from 30th March 2019, on the maximum size of the Riemann zeta function in "almost all" intervals of length 1 on the critical line. It surveys the conjecture of Fyodorov--Hiary--Keating on the behaviour of this typical maximum, as well as recent progress towards the conjecture by Najnudel and by Arguin--Belius--Bourgade--Radziwi\l\l--Soundararajan. There is also some general background discussion of the value distribution and large values of zeta.
