- W228663385 abstract "Dedicated to the memory of Batool Bagheri, the founder of mathematics house of Kerman. Abstract. Let Mn,m be the set of all nm real matrices. An nm matrix R = (rij) is g-row stochastic if Pm=1 rik is equal to 1 for all i (1 � in). Let X,Y 2 Mn,m. The matrix X is said to be gut-majorized by Y (denoted by Xgut Y ), if there exists an nn upper triangular g-row stochastic matrix R such that X = RY . Recall that a linear function T : Mn,m ! Mn,m preserves (or strongly preserves) a relation � , if TXTY whenever XY (or TXTY if and only if XY ). The present papers establishes some facts aboutgut on Mn,m, and characterizes the structure of all (strong) linear preservers ofgut on R n and strong linear preservers ofgut on Mn,m." @default.
