Fermatean fuzzy semi-prime ideals of ordered semigroups
Topological Algebra and its Applications, 2023 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.

Open Mathematics, 2015 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.

Journal of Algebra, 2004 A regular semigroup \(S\) is called \(F\)-regular if there exists a group congruence \(\rho\) on \(S\) such that every \(\rho\)-class contains a greatest element with respect to the natural partial order on \(S\). Continuing many investigations of \(F\)-regular semigroups, the authors characterize them and give a new representation of such semigroups ...

Proper Regular Semigroups [PDF]
Proceedings of the American Mathematical Society, 1978 In a recent paper, D. B. McAlister gave several characterizations of proper inverse semigroups. In this paper, the concept of proper is extended to the class of regular semigroups. This is done by requiring that the set of idempotents of the semigroup coincides with the kernel of the minimum group congruence on the semigroup.

Open Mathematics, 2018 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
International Journal of Analysis and Applications, 2022 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)

Neutrosophic ℵ −bi-ideals in semigroups [PDF]
Neutrosophic Sets and Systems, 2020 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.

Congruences on regular semigroups [PDF]
Transactions of the American Mathematical Society, 1986 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.

Flows on Classes of Regular Semigroups and Cauchy Categories
Journal of Mathematics, 2019 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.

Regular and Intra-Regular Semigroups in Terms of m-Polar Fuzzy Environment
Mathematics, 2021 The central objective of the proposed work in this research is to introduce the innovative concept of an m-polar fuzzy set (m-PFS) in semigroups, that is, the expansion of bipolar fuzzy set (BFS).
