Abstract

Abstract For X, Y ∈ Mn,m, it is said that X is g-tridiagonal majorized by Y (and it is denoted by X ≺gt Y) if there exists a tridiagonal g-doubly stochastic matrix A such that X = AY. In this paper, the linear preservers and strong linear preservers of ≺gt are characterized on Mn,m.

Mn，m上的G-三对角多数化

摘要对于X, Y∈Mn,m，如果存在一个使X = AY的三对角g双随机矩阵a，则称X是g-三对角被Y多数化的(记为X * gt Y)。本文在Mn,m上刻画了 gt的线性保持器和强线性保持器。
