چکیده
|
A matrix r is said to be g-row substochastic if re ≤ e. for x, y ∈ mn,m, it is said that x is sglt-majorized by y , x ≺sglt y , if there exists an n-by-n lower triangular g-row substochastic matrix r such that x = ry . this paper characterizes all (strong) linear preservers and strong linear preservers of ≺sglt on rn and mn,m, respectively.
