More Generalizations of Hartfiel’s Inequality and the Brunn–Minkowski Inequality

Abstract

In this note, we give some other generalizations of Hartfiel’s inequality and the Brunn–Minkowski inequality to sector matrices, the results obtained improve those of Lin (Arch Math 104:93–100, 2015) and Liu (Linear Algebra Appl 508:206–213, 2016).
