A Universal Construction for Groups Acting Freely on Real Trees
Autor: Ian Chiswell, Thomas Müller
The theory of R-trees is a well-established and important area of geometric group theory and in this book the authors introduce a construction that provides a new perspective on group actions on R-trees. They construct a group RF(G), equipped with an

Mathematical Logic
Autor: Ian Chiswell, Wilfrid Hodges
Assuming no previous study in logic, this informal yet rigorous text covers the material of a standard undergraduate first course in mathematical logic, using natural deduction and leading up to the completeness theorem for first-order logic. At each

Introduction To Lambda Trees
Autor: Ian Chiswell
The theory of Λ-trees has its origin in the work of Lyndon on length functions in groups. The first definition of an R-tree was given by Tits in 1977. The importance of Λ-trees was established by Morgan and Shalen, who showed how to compactify a ge

Compactness and local compactness for $${\mathbb{R}}$$ -trees
Autor: Ian Chiswell, Thomas Müller, Jan-Christoph Schlage-Puchta
Publikováno v: Archiv der Mathematik. 91:372-378
We establish (geometric) criteria for an $${\mathbb{R}}$$ -tree to be compact and to be locally compact. It follows that locally compact $${\mathbb{R}}$$ -trees are separable.
