Matrix inequalities for unitarily invariant norms

Jianguo Zhao

ABSTRACT:     In this study, we present some matrix inequalities for unitarily invariant norms. Firstly, we present an inequality for unitarily invariant norms. As a consequence of this result, Huang-Peng-Zou?s result follows immediately. Furthermore, we also establish inequalities for weak log-majorizations and unitarily invariant norms related to question of Bourin?s.
