Summary

We had two main aims in writing this edition:

  • Be more self-contained where possible. For instance, we have added brief overviews of Coxeter groups and root systems, and given some more details about the theory of algebraic groups.

  • While retaining the same level of exposition as in the first edition, we have given a more complete account of the representation theory of finite groups of Lie type.

In view of the second aim, we have added the following topics to our exposition:

  • We cover Ree and Suzuki groups extending our exposition of Frobenius morphisms to the case more general of Frobenius roots.

  • We have added to Harish-Chandra theory the topic of Hecke algebras and given as many results as we could easily do for fields of arbitrary characteristic prime to q, in view of applications to modular representations.

  • We have added a chapter on the computation of Green functions, with a brief review of invariant theory of reflection groups, and a chapter on the decomposition of unipotent Deligne–Lusztig characters.
