We extend the results of Csiszar (Z. Wahr. 5(1966) 279-295) to a topological semigroup S. Let μ be a measure defined on S. We consider the value of α=supKcompactlimnsupxSμn(Kx1). First. we show that the value of α is either zero or one. If α=1, we show that there exists a sequence of elements {an} In S such that μnδan converges vaguely to a probability measure where δ denotes point mass. In particular, we apply the results to inverse and matrix semigroups.
