Central Extensions and Groups with Quotients Periodic Infinite [PDF]
For an arbitrary family of groups without involutions and any Abelian group D we construct a group AD(G) such that the center of AD(G) coincides with D, and the quotient group of the group AD(G) by the subgroup D coincides with the n-periodic product of ...

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

We consider the problem of recognizing a group by its bottom layer. This problem is solved in the class of layer-finite groups. A group is layer-finite if it has a finite number of elements of every order. This concept was first introduced by S.

Commutative periodic group rings
We find a satisfactory criterion when a commutative group ring $R(G)$ is periodic only in terms of $R$, $G$ and their sections, provided that $R$ is local.

Particular Symmetries: Group Theory of the Periodic System
To this day, a hundred and fifty years after Mendeleev's discovery, the overal structure of the periodic system remains unaccounted for in quantum-mechanical terms.

Non-periodic groups with the restrictions on the norm of cyclic subgroups of non-prime order
One of the main directions in group theory is the study of the impact of characteristic subgroups on the structure of the whole group. Such characteristic subgroups include different $\Sigma$-norms of a group.
