On the anti-ramsey number of forests
WebA semigroup S is called periodic if for every element there exists such that is an idempotent. A semigroup S is called ( anti) chain-finite if S contains no infinite (anti)chains. We prove that each antichain-finite semigroup S is periodic and for every idempotent e of S the set is finite. This property of antichain-finite semigroups is used to ...
