uc-majorization and its strongly linear preservers
In this paper we introduce the concept of semimajorization as a generalized form of majorization.After that we discuss uc-majorization.For x,y ∈ R n , we say x is uc-majorized by y (written as x ≺ uc y ) if there exists an upper triangular column stochastic matrix A such that …
