چکیده
|
Miranda-thompson majorization is a group-induced cone ordering on r^n induced by the group of generalized permutation with determinants equal to 1. in this paper, we generalize miranda-thompson majorization on the matrices. for x, y є m_m,n, x is said to be miranda-thompson majorized by y (denoted by x ≺mt y) if there exists some d є conv(g) such that x = dy. also, we characterize linear preservers of this concept on m_m,n.
