Abstract

This paper aims to discuss Heinz inequalities for unitarily invariant norms.  We present some refinements of the Heinz inequalities for matrices due to Kittaneh [Integr. Equ. Oper. Theory, 68:519-527, 2010].  Our results generalize the results shown by Feng [J. Inequal. Appl., 2012:18, 2012], Wang [J. Inequal. Appl., 2013:424, 2013] and Yan et al. [J. Inequal. Appl. 2014:50, 2014].
