Interassociativity on a free commutative semigroup
A. B. Gorbatkov · Siberian Mathematical Journal · 2013
We describe all interassociates of a free commutative semigroup. Each interassociate of a free commutative semigroup is proved to be a variant of it or coincides with that semigroup. Conditions are found for the isomorphy of two variants of a free commutative semigroup.
