This is the third, substantially revised edition of this important monograph. The book is concerned with Kac–Moody algebras, a particular class of infinite-dimensional Lie algebras, and their representations. It is based on courses given over a number of years at MIT and in Paris, and is sufficiently self-contained and detailed to be used for graduate courses. Each chapter begins with a motivating discussion and ends with a collection of exercises, with hints to the more challenging problems.Read more
- Highly acclaimed in its hardback edition
- Of interest to mathematical physicists as well as algebraists
- Kac is one of the best-known names in this field; he is one of the founders of the subject
