Book DetailsMathematical Surveys and MonographsVolume: 107; 2003; 576 ppMSC: Primary 20; Secondary 17; 22
Back in print from the AMS, the first part of this book is an introduction to the general theory of representations of algebraic group schemes. Here, Janzten describes important basic notions: induction functors, cohomology, quotients, Frobenius kernels, and reduction mod \(p\), among others. The second part of the book is devoted to the representation theory of reductive algebraic groups and includes topics such as the description of simple modules, vanishing theorems, the BorelBottWeil theorem and Weyl's character formula, and Schubert schemes and line bundles on them.
This is a significantly revised edition of a modern classic. The author has added nearly 150 pages of new material describing later developments and has made major revisions to parts of the old text. It continues to be the ultimate source of information on representations of algebraic groups in finite characteristics.
The book is suitable for graduate students and research mathematicians interested in algebraic groups and their representations.

Reviews

This is an authoritative [book] which, in its updated form, will continue to be the research worker's main reference. From a practical point of view, the scheme adopted of adding new material in the final chapters and keeping the structure of the rest of the book largely unchanged is extremely convenient for all those familiar with the first edition. We are extremely lucky to have such a superb text.
Bulletin of the London Mathematical Society 
From reviews of the first edition:
Very readable ... meant to give its reader an introduction to the representation theory of reductive algebraic groups ...
Zentralblatt MATH 
Those familiar with [Jantzen's previous] works will approach this new book ... with eager anticipation. They will not be disappointed, as the high standard of the earlier works is not only maintained but exceeded ... very well written and the author has taken great care over accuracy both of mathematical details and in references to the work of others. The discussion is well motivated throughout ... This impressive and wide ranging volume will be extremely useful to workers in the theory of algebraic groups ... a readable and scholarly book.
