, 2016 Suppose that $S$ is a left amenable semitopological semigroup. We prove that if $\mathcal{S}=\{ T_{t}:t\in S\} $ is a uniformly $k$-Lipschitzian semigroup on a bounded closed and convex subset $C$ of a Hilbert space and $k< \sqrt{2}$, then the set of ...

Common fixed points in Chebyshev center for a semigroup of isometry mappings
In this article, we prove that if $K$ is a nonempty weakly compact convex set having the normal structure in a Banach space $B$ and $\mathfrak{F}$ is a left reversible semitopological semigroup of isometry mappings from $K$ into itself, then there exists

Ultrafilters on Semitopological Semigroups
Semigroup Forum, 2004It has been known since the sixties that the Stone-Čech compactification of a discrete semigroup can be given a natural structure of a compact right topological semigroup. In [\textit{N. Hindman} and \textit{D. Strauss}, Algebra in the Stone-Čech compactification: theory and applications (de Gruyter Expositions in Mathematics 27) (1998; Zbl 0918.22001)]

Every semitopological semigroup compactification of the group H + [0,1] is trivial
Semigroup Forum, 2001Let \(G=H_+[0, 1]\) be the topological group of all orientation-preserving selfhomeomorphisms of the closed interval \([0, 1]\) endowed with the compact-open topology. The author proves that every weakly almost periodic function on \(G\) is constant, and, consequently, every semitopological semigroup compactification of \(G\) is trivial.

Compactifications of semitopological semigroups
Journal of the Australian Mathematical Society, 1973Suppose S is a semitopological semigroup. We consider various subspaces of C(S) and determine what topological algebraic structure can be introduced into the spaces of means on the subspaces and into the spectra of the C*-sub-algebras of C(S) they generate.
