Algebras of right ample semigroups
Open Mathematics, 2018 Strict RA semigroups are common generalizations of ample semigroups and inverse semigroups. The aim of this paper is to study algebras of strict RA semigroups.

A groupoid approach to regular ⁎-semigroups
Advances in MathematicsIn this paper we develop a new groupoid-based structure theory for the class of regular $*$-semigroups. This class occupies something of a `sweet spot' between the important classes of inverse and regular semigroups, and contains many natural examples. Some of the most significant families include the partition, Brauer and Temperley-Lieb monoids, among

On regular semigroups II: An embedding
Journal of Pure and Applied Algebra, 1986 The core (a word suggested by Mario Petrich) of any regular semigroup S is the subsemigroup of S generated by E(S), where E(S) is the set of idempotents of S. For each \(e\in E(S)\) by \(\prec e\succ\) is denoted the core of the regular subsemigroup eSe. The main result is the following Theorem I.

The Kernel Relation for a Completely Regular Semigroup
, 1995 The kernel relation for a regular semigroup S identifies two congruences on S if they have the same kernel. It is always a complete ∧-congruence on the congruence lattice C(S) of S.

On (m, n)-ideals and (m, n)-regular ordered semigroups [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2016 Let m, n be non-negative integers. A subsemigroup A of an ordered semigroup (S, , is called an (m, n)-ideal of S if (i) Am SAn A, and (ii) if x A, y S such that y x, then y A. In this paper, necessary and sufficient conditions for every (

The Left Regular Representation of a Semigroup
, 2012 As with groups, one can study the left regular representation of a semigroup. If one considers such representations, then it is natural to ask similar questions to the group case.

Arbitrary vs. regular semigroups
, 1984 The notion of regularity for semigroups is studied, and it is shown that an unambiguous semigroup (i.e., whose L and R orders are respectively unions of disjoint trees) can be embedded in a regular semigroup with the same subgroups and the same ideal ...
