On an equivalence between regular ordered Γ-semigroups and regular ordered semigroups
Open Mathematics, 2020 In this paper, we develop a technique which enables us to obtain several results from the theory of Γ-semigroups as logical implications of their semigroup theoretical analogues.

Quasi-ideal Ehresmann transversals: The spined product structure
Open Mathematics, 2021 In any U-abundant semigroup with an Ehresmann transversal, two significant components R and L are introduced in this paper and described by Green’s ∼\sim -relations.

The product of quasi-ideal refined generalised quasi-adequate transversals
Open Mathematics, 2019 As the real common generalisations of both orthodox transversals and adequate transversals in the abundant case, the concept of refined generalised quasi-adequate transversal, for short, RGQA transversal was introduced by Kong and Wang. In this paper, an

Almost factorizable weakly type B semigroups
Open Mathematics, 2021 The definition of an almost left factorizable weakly type B semigroup is introduced by using the notion of a left factorizable weakly type B monoids, and some properties and characterizations on such semigroup are obtained.

Monoids over which all weakly flat acts are flat [PDF]
, 1990 If R is a ring with identity and M is a left R-module then it is well known that the following statements are equivalent: (1) M is flat. (2) The functor—⊗ M preserves embeddings of right ideals into R.

Idempotent Elements of Weak Projection Generalized Hypersubstitutions
Discussiones Mathematicae - General Algebra and Applications, 2018 A generalized hypersubstitution of type τ = (ni)i∈I is a mapping σ which maps every operation symbol fi to the term σ (fi) and may not preserve arity.

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 ...

Application of (m, n)-Г-Hyperideals in Characterization of LA-Г-Semihypergroups
Discussiones Mathematicae - General Algebra and Applications, 2019 In this paper, we study the concept of ordered (m, n)-Г-hyperideals in an ordered LA-Г-semihypergroup. We show that if (S, Г, ◦,⩽) is a unitary ordered LA-Г-semihypergroup with zero 0 and satisfies the hypothesis that it contains no non-zero nilpotent (m,

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 ...
