Abstract

In this paper, we present a new concept of inner amenability for a non-
empty arbitrary subset A of discrete semigroup S called A-inner amenablility. This
condition is considerably weaker than ordinary inner amenability. Further, we give
 some equivalent conditions between this version of inner amenability and Flner's
condition.
