A matrix subadditivity inequality for symmetric norms

jean-Christophe Bourin

Published 2009-06-08Version 1

Well-known subadditivity results for positive operators (of Brown-Kosaki and Rotfeld/Ando-Zhan types) are extended to Hermitian and normal ones. Applications to Cartesian decomposition and block-matrices are given.
