چکیده
|
A nonnegative square and real matrix r is a row stochastic matrix if the sum of the entries of each row is equal to one. let x, y ∈ rn. the vector x is said to be matrix majorized by y and denoted by x ≺r y if x = yr for some row stochastic matrix r. in the present paper, we characterize the linear preservers of matrix majorization t : rm → rn.
