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.

Union soft set theory applied to ordered semigroups
International 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.

Semidirect products of regular semigroups
, 1997 Within the usual semidirect product S * T of regular semigroups S and T lies the set Reg (S * T) of its regular elements. Whenever 5 or T is completely simple, Reg(S * T) is a (regular) subsemigroup.

Presentations of Completely Regular Semigroups
, 1993 The class of all completely regular semigroups, when considered as unary semigroups, forms a variety. This gives rise to questions concerning the solvability of the word problem for completely regular semigroup presentations.
