Approximation of subharmonic functions
Igor Chyzhykov
In certain classes of subharmonic functions u on C distinguished in terms of lower bounds for the Riesz measure of u, a sharp estimate is obtained for the rate of approximation by…
The continuity of the inversion and the structure of maximal subgroups in countably compact topological semigroups
Oleg V. Gutik, Dušan Pagon, Dušan Repovš
In this paper we search for conditions on a countably compact (pseudo-compact) topological semigroup under which: (i) each maximal subgroup in is a (closed) topological…
On linearly ordered -closed topological semilattices
Oleg Gutik, Dušan Repovš
We give a criterium when a linearly ordered topological semilattice is -closed. We also prove that any linearly ordered -closed topological semilattice is absolutely -clos…
On countably compact 0-simple topological inverse semigroups
Oleg Gutik, Dušan Repovš
We describe the structure of 0-simple countably compact topological inverse semigroups and the structure of congruence-free countably compact topological inverse semigroups.
Semigroup Closures of Finite Rank Symmetric Inverse Semigroups
Oleg Gutik, Jimmie Lawson, Dušan Repovš
We introduce the notion of semigroup with a tight ideal series and investigate their closures in semitopological semigroups, particularly inverse semigroups with continuous inversi…
Fréchet-Urysohn fans in free topological groups
Taras Banakh, Dušan Repovš, Lyubomyr Zdomskyy
In this paper we answer the question of T. Banakh and M. Zarichnyi constructing a copy of the Fréchet-Urysohn fan $S_\w$ in a topological group admitting a functorial embedding…
