Post Clifford semigroups, the Yang-Baxter equation, relative Rota--Baxter Clifford semigroups and dual weak left braces [PDF]
arXivAs generalizations of Rota--Baxter groups, Rota--Baxter Clifford semigroups have been introduced by Catino, Mazzotta and Stefanelli in 2023. Based on their pioneering results, in this paper we first continue to study Rota--Baxter Clifford semigroups.

Transformation Semigroups with the Deformed Multiplication [PDF]
Bulletin of the University of Kiev, Series: Physics & Mathematics,
3 (2003), 82-88 (Ukrainian), 2005 Pairwise non-isomorphic semigroups obtained from the finite inverse symmetric semigroup $\mathcal{IS}_n ,$ finite symmetric semigroup $\mathcal{T}_n$ and bicyclic semigroup by the deformed multiplication proposed by Ljapin are classified.

On Monothetic Semigroups [PDF]
Proceedings of the American Mathematical Society, 1957 By semigroup we shall mean a Hausdorff space together with a continuous associative multiplication. The study of monothetic semigroups has been initiated independently by several authors; most of the known results involve some form of compactness. We repeat here some of these known results for the sake of completeness. Among the results we establish is

On (m, n)-ideals and (m, n)-regular ordered semigroups [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2016 Let m, n be non-negative integers. A subsemigroup A of an ordered semigroup (S, , is called an (m, n)-ideal of S if (i) Am SAn A, and (ii) if x A, y S such that y x, then y A. In this paper, necessary and sufficient conditions for every (
