Epimorphisms, Closed, and Supersaturated Semigroups
Noor Alam, Noor Mohammad Khan · Communications in Algebra · 2014
We show that any almost unitary subsemigroup of a semigroup is closed in the containing semigroup and that the class of all left [right] regular semigroups is closed. Finally, we show that every globally idempotent ideal satisfying a seminormal permutation identity of a supersaturated semigroup is supersaturated.
