Totally disconnected semigroup compactifications of topological groups [PDF]
We introduce the notion of an introverted Boolean algebra $\mathcal{B}$ of closed-and-open subsets of a topological group G show that the associated Stone space $(\nu_{\mathcal{B}} G, \nu_{\mathcal{B}})$ is a totally disconnected semigroup ...

Central Sets Theorem Near of an Idempotent in Wap-Compactification
A small part of real line which is very close to zero has rich combinatorial properties. The aim of this paper is to express and then prove some locally combinatorial concepts near a virtual idempotent by considering the wap-compactification of a ...

On a topological simple Warne extension of a semigroup [PDF]
In the paper we introduce topological $\mathbb{Z}$-Bruck-Reilly and topological $\mathbb{Z}$-Bruck extensions of (semi)topological monoids which are generalizations of topological Bruck-Reilly and topological Bruck extensions of (semi)topological monoids

On a locally compact monoid of cofinite partial isometries of ℕ with adjoined zero
Let 𝒞ℕ be a monoid which is generated by the partial shift α : n↦n +1 of the set of positive integers ℕ and its inverse partial shift β : n + 1 ↦n. In this paper we prove that if S is a submonoid of the monoid Iℕ∞ of all partial cofinite isometries of ...

On feebly compact topologies on the semilattice $\exp_n\lambda$ [PDF]
We study feebly compact topologies $\tau$ on the semilattice $\left(\exp_n\lambda,\cap\right)$ such that $\left(\exp_n\lambda,\tau\right)$ is a semitopological semilattice. All compact semilattice $T_1$-topologies on $\exp_n\lambda$ are described.

Preduals of semigroup algebras [PDF]
For a locally compact group G, the measure convolution algebra M(G) carries a natural coproduct. In previous work, we showed that the canonical predual C 0(G) of M(G) is the unique predual which makes both the product and the coproduct on M(G) weak ...

Quantum Dynamical Semigroups and Decoherence
We prove a version of the Jacobs‐de Leeuw‐Glicksberg splitting theorem for weak* continuous one‐parameter semigroups on dual Banach spaces. This result is applied to give sufficient conditions for a quantum dynamical semigroup to display decoherence. The underlying notion of decoherence is that introduced by Blanchard and Olkiewicz (2003).

On Nonexpansive and Expansive Semigroup of Order-Preserving Total Mappings in Waist Metric Spaces
In this paper, we introduce nonexpansive and expansive semigroup of order-preserving total mappings (ONTn) and (OETn), respectively, to prove some fixed point theorems in waist metric spaces.
