Semigroups with inverse skeletons and Zappa-Sz'{e}p products [PDF]

Categories and General Algebraic Structures with Applications, 2013
The aim of this paper is to study semigroups possessing $E$-regular elements, where an element $a$ of a semigroup $S$ is {em $E$-regular} if $a$ has an inverse $a^circ$ such that $aa^circ,a^circ a$ lie in $ Esubseteq E(S)$. Where $S$ possesses `enough'

Semigroups Characterized by Their Generalized Fuzzy Ideals

Journal of Mathematics, 2013
We have characterized right weakly regular semigroups by the properties of their (∈,∈∨qk)-fuzzy ideals.

Regularity of Po-Γ-semigroups in Terms of Fuzzy Subsemigroups and Fuzzy Bi-ideals

Fuzzy Information and Engineering, 2015
In this paper, the notions of fuzzy subsemigroups and fuzzy bi-ideals of a po-Γ-semigroup are introduced with some of their important properties investigated. We obtain some characterizations of regular, intra-regular po-Γ-semigroups in terms of fuzzy bi-

Regular Rees matrix semigroups and regular Dubreil-Jacotin semigroups [PDF]

Journal of the Australian Mathematical Society. Series A. Pure Mathematics and Statistics, 1981
AbstractA partially ordered semigroup S is said to be a Dubreil-Jacotin semigroup if there is an isotone homomorphism θ of S onto a partially ordered group such that {} has a greatest member. In this paper we investigate the structure of regular Dubreil-Jacotin semigroups in which the imposed partial order extends the natural partial order on the ...

Feller semigroups, Lp-sub-Markovian semigroups, and applications to pseudo-differential operators with negative definite symbols [PDF]

, 2001
The question of extending L-p-sub-Markovian semigroups to the spaces L-q, q > P, and the interpolation of LP-sub-Markovian semigroups with Feller semigroups is investigated.

A groupoid approach to regular ⁎-semigroups

Advances 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

A structure theorem for completely regular semigroups

, 1987
Structure theorems for arbitrary completely regular semigroups have been given by Yamada, Warne, Petrich, and Clifford. A new structure theorem for these semigroups is proved here.
