Asymptotics of block Toeplitz determinants with piecewise continuous symbols

Abstract:

I discuss the asymptotic behavior of Toeplitz determinants with Fisher-Hartwig singularities with focus on recent joint work with Estelle Basor and Torsten Ehrhardt which deals with matrix-valued symbols that are piecewise continuous and arise in the study of entanglement
