In particular, modules over finite fields are studied, but also some applications to ordinary and Brauer characters of solvable groups are given. The authors include a proof of Brauer's height-zero conjecture and a new proof of Huppert's classification of 2-transitive solvable permutation groups.Preliminaries; 1. Solvable subgroups of linear groups; 2. Solvable permutation groups; 3. Module actions with large centralizers; 4. Prime power divisors of character degrees; 5. Complexity of character degrees; 6. p-special characters. This is a very readable and coherent expository monograph, aimed at mathematicians and advanced students who desire a thorough knowledge of some of the main topics in the representation theory of finite solvable groups. The book features complete proofs and extensive background material. David Gluck, Mathematical Reviews
