Thompson's theorem for II_1 factors

arXiv:1407.1564 · doi:10.1090/tran/6711

Abstract

A theorem of Thompson provides a non-self-adjoint variant of the classical Schur-Horn theorem by characterizing the possible diagonal values of a matrix with given singular values. We prove an analogue of Thompson's theorem for II_1 factors.
