On the Independence Number of Cayley Digraphs of Clifford Semigroups

open access: yesMathematics, 2023
Let S be a Clifford semigroup and A a subset of S. We write Cay(S,A) for the Cayley digraph of a Clifford semigroup S relative to A. The (weak, path, weak path) independence number of a graph is the maximum cardinality of an (weakly, path, weakly path ...

Metrizability of Clifford topological semigroups [PDF]

open access: yesSemigroup Forum, 2011
We prove that a topological Clifford semigroup $S$ is metrizable if and only if $S$ is an $M$-space and the set $E=\{e\in S:ee=e\}$ of idempotents of $S$ is a metrizable $G_δ$-set in $S$. The same metrization criterion holds also for any countably compact Clifford topological semigroup $S$.

Figa-Talamanca–Herz algebras for restricted inverse semigroups and Clifford semigroups

open access: yesJournal of Mathematical Analysis and Applications, 2012
The authors develop the Figa-Talamanca-Herz algebras and the space of \(p\)-pseudomeasures to inverse semigroups with restricted semigroup algebras. Let \(1 < p, q < \infty\) be such that \(\frac{1}{p}+\frac{1}{q}=1\). The Banach algebra of \(p\)-pseudomeasures \(PM_{p} (S)\) and the Figa-Talamanca-Herz algebras \(A_{q} (S)\) are defined and it is ...

Post Clifford semigroups, the Yang-Baxter equation, relative Rota-Baxter Clifford semigroups and dual weak left braces

open access: yesCommunications in Algebra
39 pages. In this version, we have mainly added content on post Clifford semigroups and braided Clifford semigroups. These form the fourth and sixth sections of the new version. We have also made necessary changes to title, the abstract, introduction and the section on relative Rota- Baxter Clifford ...

Left (Right) Regular and Transposition Regular Semigroups and Their Structures

open access: yesMathematics, 2022
Regular semigroups and their structures are the most wonderful part of semigroup theory, and the contents are very rich. In order to explore more regular semigroups, this paper extends the relevant classical conclusions from a new perspective: by ...

Congruence on a strong semilattice of π-groups

open access: yes上海师范大学学报. 自然科学版, 2022
It is well known that a semigroup is a Clifford semigroup, if and only if it is a strong semilattice of groups, and the class of π-groups is the generalization of groups in the range of π-regular semigroups.

The Clifford Deformation of the Hermite Semigroup [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2013
This paper is a continuation of the paper [arXiv:0911.4725], investigating a natural radial deformation of the Fourier transform in the setting of Clifford analysis. At the same time, it gives extensions of many results obtained in [arXiv:0907.3749].

Transposition Regular AG-Groupoids and Their Decomposition Theorems

open access: yesMathematics, 2022
In this paper, we introduce transposition regularity into AG-groupoids, and a variety of transposition regular AG-groupoids (L1/R1/LR, L2/R2/L3/R3-groupoids) are obtained. Their properties and structures are discussed by their decomposition theorems: (1)

Cross-Connections in Clifford Semigroups

open access: yes, 2023
An inverse Clifford semigroup (often referred to as just a Clifford semigroup) is a semilattice of groups. It is an inverse semigroup and in fact, one of the earliest studied classes of semigroups. In this short note, we discuss various structural aspects of a Clifford semigroup from a cross-connection perspective.
