Abstract :
In this paper we study the concept of Latin-majorization. Geometrically this concept is di erent from other kinds of majorization in some aspects. Since the set of all xs Latin-majorized by a xed y is not convex, but, consists of union of nitely many convex sets. Next, we hint to linear preservers of Latin-majorization on R^n and Mn,m.
