In our best knowledge up to now, the answer of this question is affirmative for commutative semigroups [3].
infinity]]-representation algebra R(S) of a foundation commutative semigroup S with identity.
This structure is closely related with a neutrosophic commutative semigroup, because if a Neutrosophic AG-groupoid contains a right identity, then it becomes a commutative semigroup.
This structure is closely related with a commutative semigroup, because if an -semigroup contains a right identity, then it becomes a commutative semigroup [12].
However an AG-groupoid with right identity becomes a commutative semigroup with identity e [2].
b [member of] T In particular, Let P be a Commutative semigroup.
This structure is basically a midway structure between a groupoid and a commutative semigroup.
We say G is a Smarandache commutative groupoid if there is a proper subset A of G which is a commutative semigroup under the operation of G.
If an LA-semigroup S has a right identity, then S is a commutative semigroup.
Free profinite locally idempotent and locally commutative semigroups.
Let S and T be two strongly Morita equivalent commutative semigroups with common two-sided weak local units.
They also include graphs for algebraic structures like commutative semigroups, loops, communicative groupoids, and commutative rings.
