Improvements of operator reverse AM-GM inequality involving positive linear maps

Abstract

Abstract In this paper, we shall present some reverse arithmetic-geometric mean operator inequalities for unital positive linear maps. These inequalities improve some corresponding results due to Xue (J. Inequal. Appl. 2017:283, 2017).
