On topological Brandt semigroups
Journal of Mathematical Sciences, 2012We describe the structure of pseudocompact completely 0 -simple topological inverse semigroups. We also give sufficient conditions under which the topological Brandt λ0 -extensions of an (absolutely) H-closed semigroup are (absolutely) H -closed semigroups.

Compact Topological Inverse Semigroups
Semigroup Forum, 2000A 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

INVARIANT MEASURES ON SEMIGROUPS AND IMBEDDING TOPOLOGICAL SEMIGROUPS IN TOPOLOGICAL GROUPS
Mathematics of the USSR-Sbornik, 1981In 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, 2001The 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.

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 ...

Ideal Extensions of Topological Semigroups
Canadian Journal of Mathematics, 1970In 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

Extending ideals in regular topological semigroups
Semigroup Forum, 1999The authors define three concepts of ideal extension properties of a topological semigroup \(S:S\) has the ideal extension property (IEP) if, for each closed subsemigroup \(T\) of \(S\) and each closed ideal \(I\) of \(T\), there is a closed ideal \(J\) of \(S\) such that \(J\cap T=I\).
