The structure of limit measures and their supports on topological semigroups
Let \((X_n)\) be a sequence of independent random variables taking values in a topological semigroup \(S\). Let the probability measure \(\mu_n\) be the distribution of \(X_n\). The paper aims at determining conditions under which the non-homogeneous random walk \(X_{k + 1} X_{k + 2} \cdots X_n\) converges in distribution for all \(k \geq 0\). In terms

Some Study on the Topological Structure on Semigroups
Some studies related to the topological structure of semigroups are provided. In, [3], considering and investigating the properties of the collection A of all the proper uniformly strongly prime ideals of a Γ - semigroup S, such study starts by constructing a topology τA on A using a closure operator defined in terms of the intersection and inclusion ...

The structure of topological semigroups [PDF]
The title of this address might incline one to the notion that here is to be found a small number of large theorems. To the contrary, I shall talk about a large number of small theorems.

The continuity of the inversion and the structure of maximal subgroups in countably compact topological semigroups [PDF]
In this paper we search for conditions on a countably compact (pseudo-compact) topological semigroup under which: (i) each maximal subgroup $H(e)$ in $S$ is a (closed) topological subgroup in $S$; (ii) the Clifford part $H(S)$(i.e. the union of all maximal subgroups) of the semigroup $S$ is a closed subset in $S$; (iii) the inversion $\operatorname{inv}

On the ideal structure of the semigroup of closed subsets of a topological semigroup [PDF]
Among the many semigroups which can be derived from a given compact (jointly continuous) semigroup S is the semigroup 2s consisting of its non-empty compact subsets; the product is the usual one defined by the rule EF = {xy:xεE, yεF}. The Vietoris or finite topology on 2s (in which a base for the open sets is obtained by taking all sets of the form ...

In this paper, we study the homotopy theory of single intersection graphs arising from acting spaces over topological semigroups. An acting space (S,B) is defined as a topological space B equipped with a continuous action of a topological semigroup S ...

Pseudocompact Primitive Topological Inverse Semigroups [PDF]
We study pseudocompact primitive topological inverse semigroups, describe the structure of pseudocompact primitive topological inverse semigroups, and show that the Tychonoff product of a family of pseudocompact primitive topological inverse semigroups ...

In this article, we study the homotopy aspects of intersection graphs of topological semigroups. We begin by defining the top intersection graph TGX and investigating how the algebraic and topological properties of a topological semigroup are reflected ...

Celebrating 100 years of the Banach contraction principle, we prove some fixed point theorems having all ingredients of the principle, but dealing with common fixed points of a contractive semigroup of nonlinear mappings acting in a modulated topological
