On the semigroup of injective monoid endomorphisms of the monoid with a three element family of inductive nonempty subsets of
Oleg Gutik, Marko Serivka
We describe injective monoid endomorphisms of the semigroup with a three element family of inductive nonempty subsets of . Als…
On topologization of the bicyclic monoid
Adriana Chornenka, Oleg Gutik
We construct two non-discrete inverse semigroup -topologies and a compact inverse shift-continuous -topology on the bicyclic monoid . Also we give con…
On variants of the extended bicyclic semigroup
Oleg Gutik, Kateryna Maksymyk
In the paper we describe the group of automorphisms of the extended bicyclic semigroup and study the…
Diagonal reduction of matrices over commutative semihereditary Bezout rings
Bohdan Zabavsky, Andry Gatalevych
It is proven that every commutative semihereditary Bezout ring in which any regular element is Gelfand (adequate), is an elementary divisor ring.
Stabilization with residual-free bubbles for advection-dominated transport equations
I. Kryven, V. Kukharskyy, Ya. Savula
An improved numerical scheme is proposed for advection-dominated advection-diffusion problem. The scheme is based on Galerkin finite element method (FEM) with basis enriched with a…
On a semitopological polycyclic monoid
Serhii Bardyla, Oleg Gutik
We study algebraic structure of the -polycyclic monoid and its topologizations. We show that the -polycyclic monoid for an infinite cardinal has similar…
Pseudocompactness, products and topological Brandt -extensions of semitopological monoids
Oleg Gutik, Oleksandr Ravsky
In the paper we study the preservation of pseudocompactness (resp., countable compactness, sequential compactness, -boundedness, totally countable compactness, countable pracomp…
Topological classification of zero-dimensional -groups
Taras Banakh
A topological group is called an -group if it admits a countable cover $\K$ by closed metrizable subspaces of such that a subset of is open in if and only…
