G-tridiagonal majorization on Mn,m

G-tridiagonal majorization on Mn,m

For ∈ M , it is said that is g-tridiagonal majorized by (and it is denoted by ) if there exists a tridiagonal g-doubly stochastic matrix such that = . In this paper, the linear preservers and strong linear preservers of are characterized on M
