# Geometric and Cohomological Methods in Group Theory: Solutions to Bestvina & Feighn's exercises on limit groups

@article{Wilton2009GeometricAC, title={Geometric and Cohomological Methods in Group Theory: Solutions to Bestvina \& Feighn's exercises on limit groups}, author={Henry Wilton}, journal={arXiv: Group Theory}, year={2009} }

This article gives solutions to the exercises in Bestvina and Feighn's paper on Sela's work on limit groups. We prove that all constructible limit groups are limit groups and give an account of the shortening argument of Rips and Sela.

### Limit groups over partially commutative groups and group actions on real cubings

- Mathematics
- 2015

The study of limit groups, that is, finitely generated fully residually free groups, was a key first step towards the understanding of the elementary theory of a free group. In this paper we conduct…

### THE HANNA NEUMANN CONJECTURE FOR SURFACE GROUPS

- Mathematics
- 2020

The Hanna Neumann conjecture is a statement about the rank of the intersection of two finitely generated subgroups of a free group. The conjecture was posed by Hanna Neumann in 1957. In 2011, a…

### Geometric structures on negatively curved groups and their subgroups

- Mathematics
- 2017

In this thesis, we investigate two explicit families of geometric structures that occur on hy- perbolic groups. After recalling some introductory material, we begin by giving an overview of the…

### Relative Nielsen realisation for free products

- Mathematics
- 2016

We generalise the Karrass-Pietrowski-Solitar and the Nielsen realisation theorems from the setting of free groups to that of free products. As a result, we obtain a fixed point theorem for finite…

We generalise the Karrass-Pietrowski-Solitar and the Nielsen realisation theorems from the setting of free groups to that of free products. As a result, we obtain a fixed point theorem for finite…

### On expansions of non-abelian free groups by cosets of a finite index subgroup

- Mathematics
- 2016

Let $F$ be a finitely generated non-abelian free group and $Q$ a finite quotient. Denote by $L_Q$ the language obtained by adding unary predicates $P_q$, $q\in Q$ to the language of groups. Using a…

### Magnus pairs in, and free conjugacy separability of, limit groups

- Mathematics, Chemistry
- 2016

There are limit groups having non-conjugate elements whose images are conjugate in every free quotient. Towers over free groups are freely conjugacy separable.

### A gluing theorem for negatively curved complexes

- MathematicsJ. Lond. Math. Soc.
- 2016

It is proved that, subject to certain conditions, a compact graph of spaces whose vertex spaces are negatively curved 2-complexes, and whose edge spaces are points or circles, is negatively curved, and deduce that certain groups are CAT(i1).
