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 ...

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.

Semigroup Forum, 2012
In the present paper, the properties of a locally compact Hausdorff topological Brandt semigroup, and the relation between its semigroup algebras and l1-Munn algebras over group algebras are investigated. It is proved that for each locally compact Hausdorff topological group G, and each index set I, there exists a locally compact Hausdorff topological ...

On the topologization of commutative semigroups
Mathematical Notes of the Academy of Sciences of the USSR, 1975The paper provides a sufficient feature for nondiscrete topologization of commutative semigroups as well as certain of its consequences.

Topological Groups and Semigroups
19881°. A topological group is a group endowed with a Hausdorff topology relative to which the operations of multiplication and inversion are continuous (the latter being therefore a homeomorphism); here the Cartesian product of the group with itself is endowed with the product topology.

Probability Measures on Topological Semigroups
1995This chapter forms the core of this book. It introduces and develops the key concepts, methods, and results (needed for the rest of this book) that involve convolution products of probability measures and their weak convergence. Most of the results presented here are in their final form.

On the immersion of topological semigroups in topological groups
Mathematical Notes of the Academy of Sciences of the USSR, 1969The Ore sufficient condition for imbedding of a semigroup in a group is extended to the case of topological semigroups. Imbedding conditions for a locally compact topological semigroup in a locally bicompact topological group are studied.
