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

  • 8 Accesses


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).
