open access: yes
Tyt. z nagłówka.Bibliogr. s. 195-197.In this paper, we provide existence and convergence theorems of common fixed points for left (or right) reversible semitopological semigroups of total asymptotically nonexpansive mappings in uniformly convex Banach ...

Ultrafilters on Semitopological Semigroups

Semigroup Forum, 2004
It 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)]

A Compact Monothetic Semitopological Semigroup Whose Set of Idempotents Is Not Closed

open access: yesSemigroup Forum, 2001
For every monothetic unitary group without co-compact subgroups there exists an affine compactification by a semitopological semigroup such that the set of idempotents of the semigroup is not closed. This is a negative answer to a question asked by Berglund (see Problem 29 in Ruppert's list).

Compactifications of semitopological semigroups

Journal of the Australian Mathematical Society, 1973
Suppose 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.
