On the Malcev products of some classes of epigroups, I
Open Mathematics, 2020 A semigroup is called an epigroup if some power of each element lies in a subgroup. Under the universal of epigroups, the aim of the paper is devoted to presenting elements in the groupoid together with the multiplication of Malcev products generated by ...

On a problem of M. Kambites regarding abundant semigroups [PDF]
, 2011 A semigroup is regular if it contains at least one idempotent in each -class and in each L-class. A regular semigroup is inverse if it satisfies either of the following equivalent conditions: (i) there is a unique idempotent in each -class and in each L ...

Some Innovative Types of Fuzzy Ideals in AG-Groupoids
Journal of Intelligent Systems, 2019 AG-groupoids (non-associative structure) are basic structures in Flocks theory. This theory mainly focuses on distance optimization, motion replication, and leadership maintenance with a wide range of applications in physics and biology.

A new characterization of a proper type B semigroup
Open Mathematics, 2020 In this paper, we develop the elementary theory of inverse semigroups to the cases of type B semigroups. The main aim of this paper is to study proper type B semigroups. We introduce first the concept of a left admissible triple.

Constrained abstract representation problems in semigroups and partial groupoids [PDF]
, 2004 In this paper different constrained abstract representation theorems for partial groupoids and semigroups are proved. Methods for improving the retract properties of the structures are also developed.

Veterinary Dermatology, Volume 27, Issue 5, Page 391-e98, October 2016., 2016 Backgroundā Pseudomonas aeruginosa (PA) may cause suppurative otitis externa with severe inflammation and ulceration in dogs. Multidrug resistance is commonly reported for this organism, creating a difficult therapeutic challenge. Objectiveā The aim of this study was to evaluate the in vitro antimicrobial activity of a gel containing 0.5 Āµg/mL of ...

A Short Note on Bands of Groups [PDF]
, 2015 In this paper we give necessary and sufficient conditions on a semigroup S that it be semilattice of groups, a normal band of groups, and a matrix of groups.DOI : http://dx.doi.org/10.22342/jims.21.1.151.19 ...

International Journal of Mathematics and Mathematical Sciences, Volume 20, Issue 4, Page 803-811, 1997., 1997 A comultiplication on a monoid S is a homomorphism m : S ā SāS (the free product of S with itself) whose composition with each projection is the identity homomorphism. We investigate how the existence of a comultiplication on S restricts the structure of S.
