On transformation semigroups which are ā¬š¬-semigroups
International Journal of Mathematics and Mathematical Sciences, 2006 A semigroup whose bi-ideals and quasi-ideals coincide is called a ā¬š¬-semigroup. The full transformation semigroup on a set X and the semigroup of all linear transformations of a vector space V over a field F into itself are denoted, respectively, by T(X)

Finite groups are big as semigroups [PDF]
, 2011 We prove that a finite group G occurs as a maximal proper subsemigroup of an infinite semigroup (in the terminology of Freese, Ježek, and Nation, G is a big semigroup) if and only if |G| ā„ 3.

Frequently Hypercyclic and Chaotic Behavior of Some First-Order Partial Differential Equation
Abstract and Applied Analysis, 2013 We study a particular first-order partial differential equation which arisen from a biologic model. We found that the solution semigroup of this partial differential equation is a frequently hypercyclic semigroup.

Conjugacy classes of left ideals of Sweedler's four-dimensional algebra $ H_{4} $
AIMS Mathematics, 2022 Let $ A $ be a finite-dimensional algebra with identity over the field $ \mathbb{F} $, $ U(A) $ be the group of units of $ A $ and $ L(A) $ be the set of left ideals of $ A $. It is well known that there is an equivalence relation $ \sim $ on $ L(A) $ by

Cayley graphs of basic algebraic structures [PDF]
Discrete Mathematics & Theoretical Computer Science, 2020 We present simple graph-theoretic characterizations for the Cayley graphs of monoids, right-cancellative monoids, left-cancellative monoids, and groups.

Remarks on the paper "M. Kolibiar, On a construction of semigroups" [PDF]
, 2015 In his paper "On a construction of semigroups", M. Kolibiar gives a construction for a semigroup $T$ (beginning from a semigroup $S$) which is said to be derived from the semigroup $S$ by a $\theta$-construction.

Journal of Algebra, 1998 A binomial semigroup is a semigroup with a finite set \(x_1,\dots,x_n\) of generators subject to \(\frac{n(n-1)}2\) relations of the type \(x_jx_i=x_kx_l\) with \(j>i ...

Neutrosophic LA-Semigroup Rings [PDF]
Neutrosophic Sets and Systems, 2015 Neutrosophic LA-semigroup is a midway structure between a neutrosophic groupoid and a commutative neutrosophic semigroup. Rings are the old concept in algebraic structures.

Journal of Optimization, Differential Equations and Their Applications, 2021 In this paper, we study the questions of the existence of global weak solutionsĀ and local strong solutions of paired stochastic functional differential equations in a HilbertĀ space, one of which is an equation with an unbounded operator, and the other is

Automaton semigroups: new construction results and examples of non-automaton semigroups [PDF]
, 2017 This paper studies the class of automaton semigroups from two perspectives: closure under constructions, and examples of semigroups that are not automaton semigroups.
