A semigroup S is called commuting regular if for all there exists an element
such that
This paper investigates all of the
non-abelian commuting regular inverse subsemigroups of the full
transformation semigroups
and
and determines all of them up to
isomorphisms. Moreover, the notion of commutativity degree of a finite
group will be generalized for the semigroups and it will be calculated
for the studied subsemigroups. This study gives a necessary and
sufficient condition for a commuting regular inverse semigroup to be a
group.
