Free normal complements and the unit group of integral group rings

, 1994
It is shown that there are only four finite groups G with the property that G has a nonabelian free normal complement in the unit group of the integral group ZG.

Fixed-point free pairs of homomorphisms and nonabelian Hopf-Galois structure

, 2013
Given finite groups Γ and G of order n, regular embeddings from Γ to the holomorph of G yield Hopf-Galois structures on a Galois extension L|K of fields with Galois group Γ.

The Tits alternative for generalised tetrahedron groups

, 2005
A generalised tetrahedron group is the colimit of a triangle of groups whose vertex groups are generalised triangle groups and whose edge groups are finite cyclic.

Determination of symmetry groups of 2-generator 2- groups of class two and their rationalization in molecular vibration

, 2008
Symmetry groups are powerful tools for describing the structure in physical system. The symmetry group which is composed of reflections and rotations is known as a point group.

Left-orderable groups and amenability

, 2019
This thesis provides a review of left-ordered groups and amenable groups. These are used to investigate a conjecture by Peter Linnell, which relates the existence of a nonabelian free group to a strengthening of left-orderability, by examining three ...
