On algebraic geometry over completely simple semigroups [PDF]

open access: yesInternational Journal of Group Theory, 2019
We study equations over completely simple semigroups and describe the coordinate semigroups of irreducible algebraic sets for such semigroups.

New Generalizations of sup-Hesitant Fuzzy Ideals of Semigroups

open access: yesInternational 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)

On Classification of Semigroup N by Green’s Theorem

open access: yesJournal of Mathematics, 2022
In previous papers, it has been recently defined a new class of semigroups based on both Rees matrix and completely 0-simple semigroups. For this new structure, it has been introduced with certain basic properties and finiteness conditions. The main goal

Construction of propagators for divisible dynamical maps

open access: yesNew Journal of Physics, 2021
Divisible dynamical maps play an important role in characterizing Markovianity on the level of quantum evolution. Divisible maps provide an important generalization of Markovian semigroups. Usually one analyzes either completely positive or just positive

Tropical algebra for noise removal and optimal control

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2023
Algorithms for noise removal are either complex or ineffective, and the optimal control with inequality constrains makes the algorithm even more complex.

On completely 0-simple semigroups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1996
Let S be a completely 0-simple semigroup and F be an algebraically closed field. Then for each 0-minimal right ideal M of S, M=B∪C∪{0}, where B is a right group and C is a zero semigroup.

On the Malcev products of some classes of epigroups, I

open access: yesOpen 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 ...

Some properties of finite generalized-groups [PDF]

open access: yesJournal of Mahani Mathematical Research
In this article, we discuss  the concept of completely simple-semigroups, which serves as a natural extension of the group structures. These semigroups, also known as generalized-groups, provide an interesting generalization beyond the realm of the ...

Flows on Classes of Regular Semigroups and Cauchy Categories

open access: yesJournal 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.
