Title: Modular zeros in the character table of the symmetric group

Abstract: In 2017, Miller conjectured, based on computational evidence, that for any fixed prime p the density of entries in the character table of Sn that are divisible by p goes to 1 as n goes to infinity. I’ll describe a proof of this conjecture, which is joint work with K. Soundararajan. I will also discuss the (still open) problem of determining the asymptotic density of zeros in the character table of Sn, where it is not even clear from computational data what one should expect.
