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

On Shunkov Groups Saturated with Finite Groups

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2018
The structure of the group consisting of elements of finite order depends to a large extent on the structure of the finite subgroups of the group under consideration. One of the effective conditions for investigating an infinite group containing elements

Pleistocene chronology and history of hominins and fauna at Denisova Cave. [PDF]

open access: yesNat Commun
Denisova Cave in southern Siberia is the only site known to have been occupied by Denisovans, Neanderthals and modern humans. The cave consists of three chambers (Main, East and South), with the archaeological assemblages and remains of hominins, fauna ...

On the Shunkov groups acting freely on Abelian groups

open access: yesSiberian Mathematical Journal, 2013
A group \(G\) is called a \textit{Shunkov group} if, for each finite subgroup \(F\) of \(G\), the subgroup generated by any two conjugate elements of prime order in the group \(N_G(F)/F\) is finite. With Theorem 1 the author proves that the set of elements of finite order in a Shunkov group of rank \(1\) (i.e. \(C_p\times C_p\)-free for all primes \(p\)

On Periodic Shunkov’s Groups with Almost Layer-finite Normalizers of Finite Subgroups

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2021
Layer-finite groups first appeared in the work by S.~N.~Chernikov (1945). Almost layer-finite groups are extensions of layer-finite groups by finite groups.

Locally Finite Groups Saturated with Direct Product of Two Finite Dihedral Groups

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2023
In the study of infinite groups, as a rule, some finiteness conditions are imposed. For example, the group is required to be periodic, Shunkov group, Frobenius group, locally finite group.

Properties of groups with points [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization, 2009
In this paper, we consider groups with points which were introduced by V.P. Shunkov in 1990. In Novikov-Adian's group, Adian's periodic products of finite groups without involutions and Olshansky's periodic monsters every non-unit element is a point ...

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.

On a Sufficient Condition for the Existence of a Periodic Part in the Shunkov Group

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2017
The group $ G $ is saturated with groups from the set of groups if any a finite subgroup $ K $ of $ G $ is contained in a subgroup of $ G $, which is isomorphic to some group in $ \mathfrak{X} $.
