On linear preservers of (right) matrix majorization
An \(n\times m\) real matrix \(A\) is referred to as matrix majorized (from right) by an \(n\times m\) real matrix \(B\), if there exists a row stochastic matrix \(R\) such that \(A=BR\). The authors show a few characterizions for the linear operators that preserve the matrix majorization.
