Two inequalities of unitarily invariant norms for matrices

Xuesha Wu

ABSTRACT: In this paper, we present two inequalities of matrix norms. The first one is a generalization of the inequality shown in [Math Inequal 10 (2016) 1119?1122], and the second one is a refinement of an inequality obtained by Zou [Numer Math J Chinese Univ 38 (2016) 343?349].
