Abstract:We introduce a notion of almost factorizability within the class of all locally inverse semigroups by requiring a property of order ideals, and we prove that the almost factorizable locally inverse semigroups are just the homomorphic images of Pastijn products of normal bands by completely simple semigroups.
“…Homomorphic images of Pastijn products are studied by the author in [62]. A locally inverse semigroup S is called almost factorizable if there exists a completely simple subsemigroup U in the semigroup O(S) of all order ideals of S such that E(U) = E(S) and U ⊇ S. The result obtained is an exact generalization of the characterization of almost factorizable inverse semigroups in terms of semidirect products of semilattices by groups.…”

This survey aims to give an overview of several substantial developments of the last 50 years in the structure theory of regular semigroups and to shed light on their impact on other parts of semigroup theory.
