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

open access: yes, 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 [PDF]

open access: yes, 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 ...

The Tarski Theorems and Elementary Free Groups (Algebras, logics, languages and related areas) [PDF]

open access: yes, 2018
Around 1945, Alfred Tarski proposed several questions concerning the elementary theory of non-abelian free groups. These remained open for 60 years until they were proved by O. Kharlampovich and A. Myasnikov and independently by Z. Sela.

Minimal nonmodular finite p-groups [PDF]

open access: yes, 2004
We describe first the structure of finite minimal nonmodular 2-groups G. We show that in case |G| > 25, each proper subgroup of G is Q8-free and G/(G) is minimal nonabelian of order 24 or 25.
