Abstract

In this paper we mainly discuss Heinz inequalities involving unitarily invariant norms.  By using the Hermite-Hadamard inequality, we get some refinements of the Heinz inequalities, thus new improvements of Heinz Inequalities for matrices are obtained.  Our results are different from those of [7, 1, 3, 6, 8].
