Ideal Extensions of Topological Semigroups

Canadian Journal of Mathematics, 1970
In the study of compact semigroups the constructive method rather than the representational method is usually the better plan of attack. As it was pointed out by Hofmann and Mostert in the introduction to their book [10] this method is more productive than searching for a

Enveloping semigroups in topological dynamics

Topology and Its Applications, 2007
This is a survey of the theory of enveloping semigroups in topological dynamics. We review the, already classical, theory of enveloping semigroups, due mainly to Robert Ellis, and then proceed to describe some new connections which were discovered in the

Embedding the bicyclic semigroup into countably compact topological semigroups

Topology and Its Applications, 2010
We study algebraic and topological properties of topological semigroups containing a copy of the bicyclic semigroup C(p,q). We prove that a topological semigroup S with pseudocompact square contains no dense copy of C(p,q).

INVARIANT MEASURES ON SEMIGROUPS AND IMBEDDING TOPOLOGICAL SEMIGROUPS IN TOPOLOGICAL GROUPS

Mathematics of the USSR-Sbornik, 1981
In this paper the case of topological semigroups that are cancellative and right reversible is considered. It is shown (Theorem 1) that the existence in such a semigroup of a left invariant measure satisfying certain conditions is equivalent to the imbeddability of some open ideal of the given semigroup as an open subsemigroup in a locally compact ...

Embedding of Countable Topological Semigroups in Simple Countable Connected Topological Semigroups

Journal of Mathematical Sciences, 2001
The main result of the paper is as follows. An arbitrary countable topological (inverse) semigroup is topologically isomorphically embedded into a simple countable connected Hausdorff topological (inverse) semigroup with unit.

Topology of the Semigroup of Singular Endomorphisms

SemiGroup Forum, 2000
\(\text{End}(V)\) is the semigroup of all endomorphisms of an \(n\)-dimensional vector space \(V\) over either the field \(\mathbb{R}\) of real numbers or the field \(\mathbb{C}\) of complex numbers. The subsemigroup of \(\text{End}(V)\) consisting of all singular endomorphisms is denoted by \({\mathbf S}_n\) and it is well known that \({\mathbf S}_n\)

Compact Topological Inverse Semigroups

Semigroup Forum, 2000
A topological inverse semigroup is a Hausdorff topological space together with a continuous multiplication and an inversion. With every topological inverse semigroup \(S\) one can associate its band of idempotents \(E(S)\). This paper studies compact topological inverse semigroups by relating them to their band of idempotents. Next, we describe briefly

Topological Brandt semigroups

Semigroup Forum, 2012
The author considers certain locally compact Hausdorff semi-topological Brandt semigroups \(B(G,I)\) of \(|x|\) matrix units over \(G\cup\{0\}\), where \(G\) is a locally compact Hausdorff topological group and \(I\) is an index set and studies the relation between the semigroup algebras of \(B(G,I)\) and \(I^1\)-Munn algebras over group algebras ...
