Magic squares and the symmetric group

Ofir Gorodetsky

Published 2021-02-23Version 1

Diaconis and Gamburd computed moments of secular coefficients in the CUE ensemble. We use the characteristic map to give a new combinatorial proof of their result. We also extend their computation to moments of traces of symmetric powers, where the same result holds but in a wider range.
