A fusion system over a p-group S is a category whose objects form the set of all subgroups of S, whose morphisms are certain injective group homomorphisms, and

During the last 40 years the theory of finite groups has developed dramatically. The finite simple groups have been classified and are becoming better understoo

The first book to deal comprehensively with the theory of fusion systems.

A fusion system over a p-group S is a category whose objects form the set of all subgroups of S, whose morphisms are certain injective group homomorphisms, and

For a finite group G of Lie type and a prime p, the authors compare the automorphism groups of the fusion and linking systems of G at p with the automorphism gr
