A Note on Equivalent Conditions for Majorization

Information Theory 2024-05-14 v1 math.IT

Abstract

In this paper, we introduce novel characterizations of the classical concept of majorization in terms of upper triangular (resp., lower triangular) row-stochastic matrices, and in terms of sequences of linear transforms on vectors. We used our new characterizations of majorization to derive an improved entropy inequality.
