Some faces of Smarandache semigroups' concept in transformation semigroups' approach [PDF]
, 2007 In the following text, the main aim is to distinguish some relations between Smarad- che semigroups and (topological) transformation semigroups areas.

Semigroups and their topologies arising from Green's left quasiorder
Applied General Topology, 2008 Given a semigroup (S, ·), Green’s left quasiorder on S is given by a ≤ b if a = u · b for some u ϵ S1. We determine which topological spaces with five or fewer elements arise as the specialization topology from Green’s left quasiorder for an appropriate ...

Extending binary operations to funtor-spaces
Karpatsʹkì Matematičnì Publìkacìï, 2013 Given a continuous monadic functor $T:\mathbf{Comp}\to\mathbf{Comp}$ in the category of compacta and a discrete topological semigroup $X$ we extend the semigroup operation $\varphi:X\times X\to X$ to a right-topological semigroup operation $\Phi:T\beta X\

Series with Commuting Terms in Topologized Semigroups [PDF]
Axioms, 2021 We show that the following general version of the Riemann–Dirichlet theorem is true: if every rearrangement of a series with pairwise commuting terms in a Hausdorff topologized semigroup converges, then its sum range is a singleton.

On the closure of the extended bicyclic semigroup
Karpatsʹkì Matematičnì Publìkacìï, 2013 In the paper we study the semigroup $\mathcal{C}_{\mathbb{Z}}$ which is a generalization of the bicyclic semigroup. We describe main algebraic properties of the semigroup $\mathcal{C}_{\mathbb{Z}}$ and prove that every non-trivial congruence $\mathbb{C}$

On uniformly recurrent motions of topological semigroup actions
, 2015 Let G ↷ X be a topological action of a topological semigroup $G$ on a compact metric space $X$. We show in this paper that for any given point $x$ in $X$, the following two properties that both approximate to periodicity are equivalent to each other: $

Simplicity of skew inverse semigroup rings with applications to Steinberg algebras and topological dynamics [PDF]
Forum mathematicum, 2017 Given a partial action π of an inverse semigroup S on a ring {\mathcal{A}} , one may construct its associated skew inverse

Linearizability of Non-expansive Semigroup Actions on Metric Spaces [PDF]
, 2006 We show that a non-expansive action of a topological semigroup S on a metric space X is linearizable iff its orbits are bounded. The crucial point here is to prove that X can be extended by adding a fixed point of S, thus allowing application of a ...

Brandt Extensions and Primitive Topological Inverse Semigroups
International Journal of Mathematics and Mathematical Sciences, 2010 We study (countably) compact and (absolutely) 𝐻-closed primitive topological inverse semigroups. We describe the structure of compact and countably compact primitive topological inverse semigroups and show that any countably compact primitive topological
