Extensions of semigroups by symmetric inverse semigroups of a bounded finite rank

Oleg Gutik, Oleksandra Sobol

We study the semigroup extension $I_{λ}^{n} (S)$ of a semigroup $S$ by symmetric inverse semigroups of a bounded finite rank. We describe idempotents and regular elements of t…

On feebly compact semitopological semilattice $exp_{n} λ$

Oleg Gutik, Oleksandra Sobol

We study feebly compact shift-continous topologies on the semilattice $(exp_{n} λ, \cap)$ . It is proved that such $T_{1}$ -topology is sequentially pracompact if and only if i…

On feebly compact shift-continuous topologies on the semilattice $exp_{n} λ$

Oleg Gutik, Oleksandra Sobol

We study feebly compact topologies $τ$ on the semilattice $(exp_{n} λ, \cap)$ such that $(exp_{n} λ, τ)$ is a semitopological semilattice and prove that for any shi…

On feebly compact topologies on the semilattice $exp_{n} λ$

Oleg Gutik, Oleksandra Sobol

We study feebly compact topologies $τ$ on the semilattice $(exp_{n} λ, \cap)$ such that $(exp_{n} λ, τ)$ is a semitopological semilattice. All compact semilattice $…
