On Fuzzy Weakly Completely Prime Ideal in Γ -Semigroups

open access: yesSüleyman Demirel Üniversitesi Fen-Edebiyat Fakültesi Fen Dergisi, 2010
In this paper the notion of fuzzy weakly completely prime ideal in Γ -semigroups has been introduced. Finally, the concept of operator semigroups of a -semigroup has been employed to study the relationship between their respective fuzzy weakly ...

Semigroup congruences and subsemigroups of the direct square [PDF]

open access: yes
We investigate semigroups S which have the property that every subsemigroup of S × S which contains the diagonal {(s,s):s ∈ S} is necessarily a congruence on S. We call such an S a DSC semigroup.

Topological Amenability of Semihypergroups

open access: yes, 2022
In this article, we introduce and discuss the notion of topological left amenability in the general setting of semihypergroups. We acquire several characterizations of the same in terms of certain stationary, ergodic and operator algebraic properties of ...

On Dedekind domains whose class groups are direct sums of cyclic groups

open access: yes, 2023
For a given family $(G_i)_{i \in \N}$ of finitely generated abelian groups, we construct a Dedekind domain $D$ having the following properties. \begin{enumerate} \item $\Pic(D) \cong \bigoplus_{i \in \N}G_i$.
