Abstract

In 2017, Miller conjectured, based on computational evidence, that for any fixed prime \(p\) the density of entries in the character table of \(S_n\) 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 \(S_n\), where it is not even clear from computational data what one should expect.
