Arithmetic rigidity and units in group rings
, 2001 For any finite group G the group U(Z[G]) of units in the integral group ring Z[G]is an arithmetic group in a reductive algebraic group, namely the Zariski closure of SL1 (Q[G]).

On Centralizers of Locally Finite Simple Groups
, 2019 The aim of this article is to prove the following theorem. Let G be any infinite simple locally finite group. Then, either G is isomorphic to PSL (2 , F) , where F is an infinite locally finite field, or G contains a subgroup which is the direct product ...

When Cubic is Not Isotropic: Phonon–Exciton Decoupling in CuInSnS4 Single Crystals
Advanced Optical Materials, EarlyView.A cubic CuInSnS4 crystal does not fully play by cubic rules. While phonons follow the average iso‐tropic lattice symmetry, the disorder‐localized excitons break away, showing strong, and reproduci‐ble polarization‐dependent emission. This work shows how intrinsic cation disorder can turn a mac‐roscopically cubic material into a source of hidden ...

On the generalized Fitting group of locally finite, finitary groups
, 1996 Let G be a locally finite, finitary group and F (G) the group generated by the Hirsch-Plotkin radical of G and the components of G. Our main theorem asserts that CG (F (G)) F (G). 1 Introduction The main purpose of this paper is to extend the

Outer automorphisms of locally finite p-groups
, 2003 Every group is an outer automorphism group of a locally finite p-group. This extends an earlier result [M. Dugas, R. Göbel, On locally finite p-groups and a problem of Philip Hall's, J.

Information Transmission Strategies for Self‐Organized Robotic Aggregation
Advanced Robotics Research, EarlyView.In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Ends of groups : a computational approach [PDF]
We develop ways in which we can find the number of ends of automatic groups and groups with solvable word problem. In chapter 1, we provide an introduction to ends, splittings, and computa- tion in groups. We also remark that the `JSJ problem'

Locally finite groups whose subgroups have finite normal oscillation
, 2014 If \(X\) is a subgroup of a group \(G\), the cardinal number \(min\{ |X:X_G|,X^G:X|\}\) is called the normal oscillation of \(X\) in \(G\). It is proved that if all subgroups of a locally finite group \(G\) have finite normal oscillation, then \(G ...

Advanced Robotics Research, EarlyView.To address challenges in high‐throughput intestinal sampling with sealed containment and target drug delivery, we developed a dual‐functional ingestible passive capsule with a dual‐triggered control system based on pH‐response and mechanical actuation.

On Shunkov Groups Saturated with Finite Groups
Известия 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
