On Periodic Groups and Shunkov Groups that are Saturated by Dihedral Groups and $A_5$
A group is said to be periodic, if any of its elements is of finite order. A Shunkov group is a group in which any pair of conjugate elements generates Finite subgroup with preservation of this property when passing to factor groups by finite Subgroups ...

On Periodic Groups of Shunkov with the Chernikov Centralizers of Involutions
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.

Optimal periodic output feedback control: a continuous-time approach [PDF]
: This paper addresses the problem of optimal static output feedback control of linear periodic systems. The proposed approach, which allows to deal with both stable and unstable open loop systems, relies on a continuous-time formulation of the control ...

A new description of equivariant cohomology for totally disconnected groups [PDF]
We consider smooth actions of totally disconnected groups on simplicial complexes and compare different equivariant cohomology groups associated to such actions.

Properties of groups with points [PDF]
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 ...

On Periodic Groups Isospectral to A7 [PDF]
The spectrum of a periodic group $G$ is the set $ω(G)$ of its element orders. Consider a group $G$ such that $ω(G)=ω(A_7)$. Assume that $G$ has a subgroup $H$ isomorphic to $A_4$, whose involutions are squares of elements of order $4$. We prove that either $O_2(H) \subseteq O_2(G)$ or $G$ has a finite nonabelian simple subgroup.

Some classes of minimally almost periodic topological groups
A Hausdorff topological group G=(G,T) has the small subgroup generating property (briefly: has the SSGP property, or is an SSGP group) if for each neighborhood U of $1_G$ there is a family $\sH$ of subgroups of $G$ such that $\bigcup\sH\subseteq U$ and $\

Visual evoked potentials (VEPs) to periodic stimuli are commonly used in brain computer interfaces for their favorable properties such as high target identification accuracy, less training time, and low surrounding target interference.

On solving periodic Riccati equations [PDF]
Numerically reliable algorithms to compute the periodic non-negative definite stabilizing solutions of the periodic differential Riccati equation (PRDE) and discrete-time periodic Riccati equation (DPRE) are proposed. For the numerical solution of PRDEs,
