This book contains the proceedings of the conference "Groups and Model Theory", held May 30-June 3, 2011, in Ruhr, Germany, in honour of Rudiger Gobel'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...
