Сенашов, Владимир Иванович. On periodic groups of Shunkov with the Chernikov centralizers of involutions [Текст] / Владимир Иванович Сенашов // Bulletin of Irkutsk State University,: Series Mathematics. — 2020. — Т. 32. — С. 101-117Аннотация:
Layer-finite groups for the first time appeared in the article of S.~N.~Chernikov (1945). Almost layer-finite groups are extensions of a layer-finite groups by finite groups. The author develops the direction of characterizations of known well studied classes of groups in other classes of groups with some additional (rather weak) finiteness conditions. In this paper almost layer-finite groups receive characterization in the class of periodic Shunkov groups. Shunkov group is a group $G$ in which for any of its finite subgroup~$ K $ in the factor group $N_G (K) / K$
any two conjugate elements of prime order generate a finite subgroup. We study periodic Shunkov's groups with the condition: normalizer of any finite non-unit subgroup is almost layer-finite. It is proved that if in such group the centralizers of involutions are Chernikov, then the group is almost layer-finite.

On the Equationally Artinian Groups
Shahryari, Mohammad; Tayyebi, Javad; Шахрияри, Мохаммад; Тайеби, Джавад (Сибирский федеральный университет. Siberian Federal University, 2020-09)In this article, we study the property of being equationally Artinian in groups. We define the radical topology corresponding to such groups and investigate the structure of irreducible closed sets of these topologies. ... -
Sharply 3-transitive Groups with Finite Element
Durakov, Evgeny B.; Дураков, Евгений Б. (Сибирский федеральный университет. Siberian Federal University, 2021-04)In this paper we study sharply 3-transitive groups. The local finiteness of sharply triply transitive permutation groups of characteristic p > 3 containing a finite element of order p is proved. Keywords: group, sharply ... -

Problems of Bounding the p-Length and Fitting Height of Finite Soluble Groups
Khukhro, Evgeny I.; Хухро, Евгений И. (Сибирский федеральный университет. Siberian Federal University., 2013-11)This paper is a survey of some open problems and recent results about bounding the Fitting height and p-length of finite soluble groups. In many problems of finite group theory, nowadays the classification greatly ...
