Discrete Cocompact Subgroups of the Five-Dimensional Connected and Simply Connected Nilpotent Lie Groups

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2009
The discrete cocompact subgroups of the five-dimensional connected, simply connected nilpotent Lie groups are determined up to isomorphism. Moreover, we prove if G = N × A is a connected, simply connected, nilpotent Lie group with an Abelian factor A ...

Dihedral and Quaternion Autotopism Subgroups of Semifield Projective Planes of Order $p^4$

open access: yesИзвестия Иркутского государственного университета: Серия "Математика"
Dihedral and Quaternion Autotopism Subgroups of Semifield Projective Planes of Order $p^4$}In 1959, D.R.~Hughes conjecture that the full collineation group of any finite non-Desarguesian semifield projective plane is solvable (see also the question 11.76

Elementary abelian subgroups of classical groups

open access: yes
The main problems considered in the thesis are the following: (1) Classify the nontoral elementary abelian p-subgroups of the simple algebraic groups G of types A, B, C and D over an algebraically closed field K of characteristic different from the prime

On Groups with Minimality Condition for Noninvariant Abelian pd-Subgroups

open access: yes, 2005
Вивчаються властивості i будова неабелевих груп з умовою мінімальності для неінваріантних абелевих pd-підгруп, якщо вони не задовольняють умову мінімальності для абелевих pd-підгруп.

The characteristic subgroups of an abelian p-group

open access: yesJournal of Algebra
All groups in this review are primary abelian groups. In the world-famous monograph of \textit{I. Kaplansky} [Infinite abelian groups. Ann Arbor, MI: University of Michigan Press (1954; Zbl 0057.01901)] the following was proved: If \(G\) is a transitive \(p\)-group and \(p\ne2\), then \(G\) is necessarily fully transitive and its characteristic ...
