A Lieb-Thirring inequality for singular values

Functional Analysis 2011-04-28 v1

Abstract

Let AA and BB be positive semidefinite matrices. We investigate the conditions under which the Lieb-Thirring inequality can be extended to singular values. That is, for which values of pp does the majorisation σ(BpAp)wσ((BA)p)\sigma(B^p A^p) \prec_w \sigma((BA)^p) hold, and for which values its reversed inequality σ(BpAp)wσ((BA)p)\sigma(B^p A^p) \succ_w \sigma((BA)^p).
