C*-algebras of Clifford semigroups

Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 1989
SynopsisWe investigate algebras associated with a (discrete) Clifford semigroupS =∪{Ge: e ∈ E{. We show that the representation theory forSis determined by an enveloping Clifford semigroupUC(S) =∪{Gx: x ∈ X} whereXis the filter completion of the semilatticeE.We describe the representation theory in terms of both disintegration theory and sheaf theory.

Clifford semigroups as functors and their cohomology

Semigroup Forum, 2011
Let \(\mathcal C\) be a category. The `diagram category' \(Dg(\mathcal C)\) has functors \(T\colon\Sigma\to\mathcal C\) where \(\Sigma\) is a small category as its objects and certain natural transformations as its morphisms. For a semilattice \(E\) regarded as a category, a functor \(F\colon E\to\mathbf{Grp}\) is called a `semilattice imbedding' if ...

LeftRight Clifford Semigroups

Springer Proceedings in Mathematics and Statistics, 2015
Clifford semigroups are certain interesting class semigroups and looking for regular semigroups close to this is natural. Here we discuss the leftright Clifford semigroups.

On the endomorphism monoids of Clifford semigroups

Asian-European Journal of Mathematics, 2018
In this paper, we study properties of the endomorphism monoids of strong semilattices of groups. In Sec. 2, several properties for endomorphism monoids of finite semilattices are investigated. In Sec. 3, we collect some results on endomorphism monoids of strong semilattices of groups, i.e. Clifford semigroups.

Clifford semigroups of ideals in monoids and domains

Forum Mathematicum, 2009
The author studies the problem when the ideal semigroup and the ideal class semigroup related to an ideal system on a monoid (or a domain) are Clifford or Boolean semigroups. Namely, he investigates the cases of valuation monoids and Prüfer-like monoids.

Rota–Baxter operators on Clifford semigroups and the Yang–Baxter equation

Journal of Algebra, 2023
In this paper, we introduce the theory of Rota-Baxter operators on Clifford semigroups, useful tools for obtaining dual weak braces, i.e., triples $\left(S,+,\circ\right)$ where $\left(S,+\right)$ and $\left(S,\circ\right)$ are Clifford semigroups such ...

Clifford semigroup actions

Asian-European Journal of Mathematics, 2022
In this paper, we establish the orbit-stabilizer theorem and the orbit decomposition theorem for a Clifford semigroup. Moreover, we establish that for a Clifford semigroup [Formula: see text], any two homogeneous Clifford [Formula: see text]-sets [Formula: see text] and [Formula: see text] are Clifford [Formula: see text]-isomorphic if and only if for
