Congruences on regular semigroups [PDF]
Let S S be a regular semigroup and let ρ \rho be a congruence relation on S S . The kernel of ρ \rho , in notation ker ρ \ker \rho , is the union of the idempotent ρ \rho -classes.

RIGHT PURE UNI-SOFT IDEALS OF ORDERED SEMIGROUPS [PDF]
In this paper, we initiate the study of pure uni-soft ideals in ordered semigroups. The soft version of right pure ideals in ordered semigroups is considered which is an extension of the concept of right pure ideal in ordered semigroups. We also give the

Fermatean fuzzy semi-prime ideals of ordered semigroups
Fermatean fuzzy sets (FFSs) are invented to resolve the underlying limitations of intuitionistic fuzzy sets and Pythagorean fuzzy sets. The major goal of this study is to introduce Fermatean fuzzy semi-prime ideals of ordered semigroups.

The algebra of adjacency patterns: Rees matrix semigroups with reversion [PDF]
We establish a surprisingly close relationship between universal Horn classes of directed graphs and varieties generated by so-called adjacency semigroups which are Rees matrix semigroups over the trivial group with the unary operation of reversion.

In this paper, we give some new characterizations of orthodox semigroups in terms of the set of inverses of idempotents. As a generalization, a new class of regular semigroups, namely Vn-semigroups, is introduced.

Neutrosophic ℵ −bi-ideals in semigroups [PDF]
In this paper, we introduce the notion of neutrosophic ℵ-bi-ideal for a semigroup. We infer different semigroups using neutrosophic ℵ -bi-ideal structures.

Amenability and geometry of semigroups [PDF]
We study the connection between amenability, Følner conditions and the geometry of finitely generated semigroups. Using results of Klawe, we show that within an extremely broad class of semigroups (encompassing all groups, left cancellative semigroups ...

In this paper, we give some characterizations of 𝓠-regular semigroups and show that the class of 𝓠-regular semigroups is closed under the direct product and homomorphic images.

New Generalizations of sup-Hesitant Fuzzy Ideals of Semigroups
As general concepts of sup-hesitant fuzzy right (resp., left, interior, two-sided) ideals of semigroups, the concepts of sup+α-hesitant fuzzy right (resp., left, interior, two-sided) ideals and sup-β-hesitant fuzzy right (resp., left, interior, two-sided)

Flows on Classes of Regular Semigroups and Cauchy Categories
We consider the structure of the flow monoid for some classes of regular semigroups (which are special case of flows on categories) and for Cauchy categories.
