Introduction to Lie algebras and representation theory

Graduate Texts in Mathematics #9

by James E. Humphreys

This book is designed to introduce the reader to the theory of semisimple Lie algebras over an algebraically closed field of characteristic 0, with emphasis on representations. A good knowledge of linear algebra (including eigenvalues, bilinear forms, Euclidean spaces, and tensor products of vector spaces) is presupposed, as well as some acquaintance with the methods of abstract algebra. The first four chapters might well be read by a bright undergraduate; however, the remaining three chapters are more demanding. This text grew out of lectures which the author gave at the N.S.F. Advanced Science Seminar on Algebraic Groups at Bowdoin College in 1968.

This is a great introduction to Lie Algebras and Representation Theory as the title claims, and probably the best textbook currently in existence (although perhaps combining this book with Fulton & Harris would make it even better). The book is, however, very dense -- partly due to the fact that the subject is somewhat computational (as are most of the classification theorems), but also many proofs in the book are far from optimal and can be simplified greatly. As a result, it takes longer to read than it actually should.

Nice but difficult book. The topic treated is a complex one, but I think he gives some intuition in introducing concepts (at least in the first two chapters). Such as why Engels or Lies theorem, why sl(2,C) is so important, or why the adjoint rep, and many more. Maybe the universal enveloping algebra or the Verma modules should be read somewhere else. From section 4 everything becomes tedious. But all in all, is a really abstract topic what we are dealing with, and the book relies on rigor

finished chapter 1 - 4 and some parts of chapter 5. The proofs in this book are not easy to read, but they deserve some time to digest.

Remarkably readable and a good reference.

Совершенно замечательное изложения теории алгебр Ли. В ВЕСЬМА тонкой книжке содержится ряд общих фактов (теорема Энгеля, теорема Ли, критерий Картана), ПОЛНАЯ классификация полупростых комплексных алгебр Ли и систем корней, теория представлений полупростых алгебр Ли и - внимание! - построение групп Шевалле любого типа над произвольным полем.

МНОЖЕСТВО упражнений позволят любому читателю стать вполне familiar с основами теории алгебр Ли.
