A groupoid approach to regular ⁎-semigroups

open access: yesAdvances in Mathematics
In 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

Union soft set theory applied to ordered semigroups

open access: yesInternational Journal of Analysis and Applications, 2020
The uni-soft type of bi-ideals in ordered semigroup is considered. The notion of a uni-soft bi-ideal is introduced and the related properties are investigated.

On regular semigroups II: An embedding

open access: yesJournal 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.

On intra-regular ordered semigroups

open access: yesSemigroup Forum, 1993
The author continues her studies of partially ordered semigroups \(S\) which are intraregular, that is, for every \(a\in S\) there are \(x,y\in S\) such that \(a\leq xa^ 2 y\) [see the author, Semigroup Forum 44, 341-346 (1992; Zbl 0756.06008)]. It is shown (similar to the purely semigroup theoretical case) that a p.o.
