On continuity of homomorphisms between topological Clifford semigroups

Karpatsʹkì Matematičnì Publìkacìï, 2014
Generalizing an old result of Bowman we prove that a homomorphism $f:X\to Y$ between topological Clifford semigroups is continuous if • the idempotent band $E_X=\{x\in X:xx=x\}$ of $X$ is a $V$-semilattice; • the topological Clifford semigroup

On locally compact shift continuous topologies on the semigroup $\boldsymbol{B}_{[0,\infty)}$ with an adjoined compact ideal

Математичні Студії
Let $[0,\infty)$ be the set of all non-negative real numbers. The set $\boldsymbol{B}_{[0,\infty)}=[0,\infty)\times [0,\infty)$ with the following binary operation $(a,b)(c,d)=(a+c-\min\{b,c\},b+d-\min\{b,c\})$ is a bisimple inverse semigroup.

(L)-Semigroup Sums

Axioms, 2018
An (L)-semigroup S is a compact n-manifold with connected boundary B together with a monoid structure on S such that B is a subsemigroup of S. The sum S + T of two (L)-semigroups S and T having boundary B is the quotient space obtained from the ...

A bridge theorem for the entropy of semigroup actions

Topological Algebra and its Applications, 2020
The topological entropy of a semigroup action on a totally disconnected locally compact abelian group coincides with the algebraic entropy of the dual action.

Constructions of positive commutative semigroups on the plane, II

International Journal of Mathematics and Mathematical Sciences, 1985
A positive semiroup is a topological semigroup containing a subsemigroup N isomorphic to the multiplicative semigroup of nonnegative real numbers, embedded as a closed subset of E2 in such a way that 1 is an identity and 0 is a zero.

Certain semigroups embeddabable in topological groups [PDF]

Journal of the Australian Mathematical Society. Series A. Pure Mathematics and Statistics, 1982
AbstractIn this paper we study commutative topological semigroups S admitting an absolutely continuous measure. When S is cancellative we show that S admits a weaker topology J with respect to which (S, J) is embeddable as a subsemigroup with non-empty interior in some locally compact topological group.

On representation of semigroups of inclusion hyperspaces

Karpatsʹkì Matematičnì Publìkacìï, 2010
Given a group $X$ we study the algebraic structure of the compactright-topological semigroup $G(X)$ consisting of inclusionhyperspaces on $X$. This semigroup contains the semigroup$lambda(X)$ of maximal linked systems as a closed subsemigroup.We ...

A note on conservative measures on semigroups

International Journal of Mathematics and Mathematical Sciences, 1992
Consider (S,B,μ) the measure space where S is a topological metric semigroup and μ a countably additive bounded Borel measure. Call μ conservative if all right translations tx:s→sx, x∈S (which are assumed closed mappings) are conservative with respect (S,
