Abstract

T‎he commutativity‎ degree of a finite non-commutative semigroup S is defined to be the probability‎ of choosing a pair (x,y) of the elements of S such that x commutes with y‎. Obviously if S is a abelian semigroup, then commutativity degree of S is 1. In this study, we consider semigroups are non-commutative and finite. ‎For a given positive integer n=p^α q^β where p and q are primes (2≤p
