# Groups and Model Theory

This book contains the proceedings of the conference “Groups and Model
Theory”, held May 30–June 3, 2011, in Ruhr, Germany, in honor of
Rüdiger Göbel's 70th birthday.

In the last thirty years, group theory has received new input
through the application of methods from logic to problems in
algebra. In particular, model theory has strongly influenced both
commutative and non-commutative group theory. This led to striking new
developments in group theory and has had an interesting impact back on
model theory. This interplay has been revisited by algebraists and
model theorists and is showing strong and promising roads for future
research.

This book presents important current research at the border of
model theory and group theory by renowned researchers. Articles in
this volume cover abelian groups, modules over commutative rings,
permutation groups, automorphism groups of homogeneous structures such
as graphs, relational structures, geometries, topological spaces or
groups, consequences of model theoretic properties like stability or
categoricity, subgroups of small index, the automorphism tower
problem, as well as random constructions.

#### Readership

Graduate students and research mathematicians interested in group theory and model theory.
