Abstract

Let A B denote the Hadamard product of A and B A B the same size complex matrices. let σ(A) denote the singular value vector of A. with components in decreasing order and let M_n (C) denote the space of all complex n×n matrices. This paper gives another proof of singular value inequality

σ(A B)≺_ω σ(A) σ(B)

for any A B∈M_n (C), which has been obtained recently in {1, 3, 4, 7].
