Abstract

We discuss asymptotics of Toeplitz determinants with Fisher-Hartwig singularities, with emphasis on asymptotics which are uniform with respect to the location of the singularities. These are used to prove a conjecture by Fyodorov and Keating concerning the asymptotics of moments of certain averages of the characteristic polynomial of the CUE.
