Almost periodic compactifications of group extensions [PDF]
, 2002 summary:Let $N$ and $K$ be groups and let $G$ be an extension of $N$ by $K$. Given a property $\mathcal P$ of group compactifications, one can ask whether there exist compactifications $N^{\prime }$ and $K^{\prime }$ of $N$ and $K$ such that the ...

Group Theoretical Description of the Periodic System
, 2022 The group theoretical description of the periodic system of elements in the framework of the Rumer–Fet model is considered. We introduce the concept of a single quantum system, the generating core of which is an abstract C*-algebra.

On Periodic Groups and Shunkov Groups that are Saturated by Dihedral Groups and $A_5$
Известия Иркутского государственного университета: Серия "Математика", 2017 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 ...

Groups with Subnormal Deviation
Mathematics, 2023 The structure of groups which are rich in subnormal subgroups has been investigated by several authors. Here, we prove that if a periodic soluble group G has subnormal deviation, which means that the set of its non-subnormal subgroups satisfies a very ...

Periodic Algebras Generated by Groups [PDF]
Algebra Colloquium, 2015 We consider algebras with basis numerated by elements of a group G. We fix a function f from G × G to a ground field and give a multiplication of the algebra which depends on f. We study the basic properties of such algebras. In particular, we find a condition on f under which the corresponding algebra is a Leibniz algebra.

Properties of groups with points [PDF]
Iranian 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 ...

The p-period of an infinite group [PDF]
Publicacions Matemàtiques, 1992 A group \(\Gamma\) has virtual cohomological dimension \(\operatorname{vcd}n\) if \(\Gamma\) has a subgroup of finite index which has cohomological dimension \(n\). For such groups the Farrell cohomology \(\widehat{H}^ i(\Gamma,-)\) is defined which has formal properties analogous to those of the Tate cohomology for finite groups (in which case \(n=0\))

On a Sufficient Condition for the Existence of a Periodic Part in the Shunkov Group
Известия 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} $.

The State Space Subdivision Filter for Estimation on SE(2)
Sensors, 2021 The SE(2) domain can be used to describe the position and orientation of objects in planar scenarios and is inherently nonlinear due to the periodicity of the angle.

Dynamic, capability-driven scheduling of DAG-based real-time jobs in heterogeneous cluster [PDF]
, 2004 In this research a scenario is assumed where periodic real-time jobs are being run on a heterogeneous cluster of computers, and new aperiodic parallel real-time jobs, modelled by Directed Acyclic Graphs (DAG), arrive at the system dynamically.
