Upper capacity entropy and packing entropy of saturated sets for amenable group actions

open access: yesDiscrete and Continuous Dynamical Systems, 2023
Let $(X,G)$ be a $G$-action topological system, where $G$ is a countable infinite discrete amenable group and $X$ a compact metric space. In this paper we study the upper capacity entropy and packing entropy for systems with weaker version of specification.

On Periodic Groups Saturated with Finite Frobenius Groups

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2021
A group is called weakly conjugate biprimitively finite if each its element of prime order generates a finite subgroup with any of its conjugate elements. A binary finite group is a periodic group in which any two elements generate a finite subgroup. If $

On Two Properties of Shunkov Group

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2021
One of the interesting classes of mixed groups ( i.e. groups that can contain both elements of finite order and elements of infinite order) is the class of Shunkov groups. The group $G$ is called Shunkov group if for any finite subgroup $H$ of $G$ in the

Groups with a Strongly Embedded Subgroup Saturated with Finite Simple Non-abelian Groups

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2020
An important concept in the theory of finite groups is the concept of a strongly embedded subgroup. The fundamental result on the structure of finite groups with a strongly embedded subgroup belongs to M. Suzuki.

Localizations of a Ring at Localizable Sets, their Groups of Units and Saturations

open access: yesMathematics in Computer Science, 2022
AbstractWe continue to develop the most general theory of one-sided fractions started in Bavula (Localizable sets and the localization of a ring at a localizable set. arXiv:2112.13447). The aim of the paper is to introduce 10 types of saturations of a set in a ring and using them to study localizations of a ring at localizable sets, their groups of ...
