C0-continuity of the Fröbenius-Perron semigroup
International Journal of Mathematics and Mathematical Sciences, 2002 We consider the Fröbenius-Perron semigroup of linear operators associated to a semidynamical system defined in a topological space X endowed with a finite or a σ-finite regular measure.

On topological McAlister semigroups
Journal of Pure and Applied Algebra, 2023 In this paper we consider McAlister semigroups over arbitrary cardinals and investigate their algebraic and topological properties. We show that the group of automorphisms of a McAlister semigroup $\mathcal{M}_λ$ is isomorphic to the direct product $Sym(λ){\times}\mathbb{Z}_2$, where $Sym(λ)$ is the group of permutations of the cardinal $λ$.

Journal of Mathematics, Volume 2026, Issue 1, 2026.This paper advances the theory of bipolar Pythagorean neutrosophic fuzzy (BPNF) sets by establishing their formalization within a topological and metric framework, while also demonstrating their role in decision‐making under uncertainty. The main contributions are as follows: (1) definition and characterization of BPNF topological spaces, providing a ...

, 2015 Let S be a semigroup, C(S) the automaton constructed from the right Cayley graph of S with respect to all of S as the generating set and ∑(C(S)) the automaton semigroup constructed from C(S). Such semigroups are termed Cayley automaton semigroups. For

Journal of Mathematics, Volume 2026, Issue 1, 2026.In this article, we analyze the effect of geometric nonlinearity on stability results for extensible nonsymmetric two beams in a bounded domain. Two internal frictional dampings are present together with two fractional time delays. The equations describe a system consisting of two elastically coupled extensible beams, to which uniform damping terms and

Embedding topological semigroups in topological groups [PDF]
Semigroup Forum, 1970 In [6] Rothman investigated the problem of embedding a topological semigroup in a topological group. He defined a concept calledProperty F and showed that Property F is a necessary and sufficient condition for embedding a commutative, cancellative topological semigroup in its group of quotients as an open subset.

Topological and ditopological unosemigroups [PDF]
Математичні Студії, 2013 In this paper we introduce and study a new topologo-algebraic structure called a (di)topological unosemigroup. This is a topological semigroup endowed with continuous unary operations of left and right units (which have certain continuous division ...

On locally compact semitopological O-bisimple inverse ω-semigroups
Topological Algebra and its Applications, 2018 We describe the structure of Hausdorff locally compact semitopological O-bisimple inverse ω- semigroups with compact maximal subgroups. In particular, we show that a Hausdorff locally compact semitopological O-bisimple inverse ω-semigroup with a compact ...
