Subdirect decompositions of finite commutative semigroups.
Subdirect decompositions of finitely generated commutative semigroups.
Subdirect products of a band and a semigroup.
Subdirect products of regular seimgroups.
Subdirectly irreducible completely symmetrical semigroups.
Subdirectly irreducible groupoids in some varieties
Subdirectly irreducible H-semigroups.
Subdirectly irreducible non-idempotent left symmetric left distributive groupoids
We study groupoids satisfying the identities x·xy = y and x·yz = xy·xz. Particularly, we focus our attention at subdirectlyirreducible ones, find a description and charecterize small ones.
