Abstract :
Let c0 be the real vector space of all real sequences which
converge to zero. For every x, y 2 c0, it is said that y is block diagonal
majorized by x (written y b x) if there exists a block diagonal row
stochastic matrix R such that y = Rx. In this paper we find the possible
structure of linear functions T : c0 ! c0 preserving b.
