 Apr15 comment Variety of commutative semi group @J.-E.Pin You are right, I have no idea what the difference between an identity and a relation may be in the context here. Apr15 comment Variety of commutative semi group Judging from the result that you expect, I'm suspecting that you are after the variety of a commutative semigroup ring? Maybe one that satisfies $x_i^2 = x_i^3$ for each indeterminate $x_i$? Please rework this questions, at the moment it makes no sense.
