Soft Intersection Bi-interior Ideals of Semigroups

open access: yesJournal of Innovative Science and Engineering
Generalizing the ideals of an algebraic structure has shown to be both beneficial and interesting for mathematicians. In this context, the idea of the bi-interior ideal was introduced as a generalization of the bi-ideal and interior ideal of a semigroup.

Recurrency on the Space of Hilbert-Schmidt Operators

open access: yesمجلة بغداد للعلوم
In this paper, it is proved that if a C0-semigroup is chaotic, hypermixing or supermixing, then the related left multiplication C0-semigroup on the space of Hilbert-Schmidt operators is recurrent if and only if it is hypercyclic. Also, it is stated that

The Ellis semigroup of a nonautonomous discrete dynamical system

open access: yes, 2016
We introduce the {\it Ellis semigroup} of a nonautonomous discrete dynamical system $(X,f_{1,\infty})$ when $X$ is a metric compact space. The underlying set of this semigroup is the pointwise closure of $\{f\sp{n}_1 \, |\, n\in \mathbb{N}\}$ in the ...

A stability theorem for convergence of a lyapounov function along trajectories of nonexpansive semigroups

open access: yesElectronic Journal of Differential Equations, 2006
It is known that a regularly Lyapounov function for a semigroup of contractions on a Hilbert space converges to its minimum along the trajectories of the semigroup.

McAlister Semigroups

open access: yesJournal of Algebra, 1998
For a positive integer \(n\), let \(\Sigma_n\) denote the alphabet consisting of letters \(x_0,x_1,\dots,x_{n-1}\). A triple \((\alpha,\beta,\gamma)\) of words over \(\Sigma_n\) is allowable if \(\alpha\) is a prefix of \(\beta\) and \(\gamma\) is a suffix of \(\beta\). Let \((\alpha,\beta,\gamma)\) and \((\alpha',\beta',\gamma')\) be allowable triples
