Topological Grading of Semigroup C*-Algebras
, 2020The paper deals with the abelian cancellative semigroups and the reduced semigroup C*-algebras. It is supposed that there exist epimorphisms from the semigroups onto the group of integers modulo n.

On the measure-theoretic entropy and topological pressure of free semigroup actions
Ergodic Theory and Dynamical Systems, 2016In this paper we introduce the notions of topological pressure and measure-theoretic entropy for a free semigroup action. Suppose that a free semigroup acts on a compact metric space by continuous self-maps.

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 ...

Right-topological semigroup operations on inclusion hyperspaces
Matematychni Studii, 2008We show that for any discrete semigroup $X$ the semigroup operation can be extended to a right-topological semigroup operation on the space $G(X)$ of inclusion hyperspaces on $X$. We detect some important subsemigroups of $G(X)$, study the minimal ideal,

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 ...

Topological properties of semigroup primes of a commutative ring
, 2017A semigroup prime of a commutative ring R is a prime ideal of the semigroup $$(R,\cdot )$$(R,ยท). One of the purposes of this paper is to study, from a topological point of view, the space $${\varvec{\mathcal {S}}}(R)$$S(R) of prime semigroups of R.
