MATH 649 — Fall 2000
Lie Algebras

Lie groups, Lie algebras and their representations play an important role in much of mathematics, particularly in number theory, mathematical physics and topology.

This is a basic course in Lie algebras. The prerequisites are a basic knowledge of algebra and linear algebra at the honors undergraduate level. The first five topics are standard. I hope to be able to devote substantial time to the last one. Ken Brown will teach a course on Kac-Moody algebras in the spring.

• Basic structure and properties of Lie algebras; theorems of Lie and Engel.
• Nilpotent solvable and reductive Lie algebras.
• Enveloping Algebras and Differential Operators
• The structure of semisimple algebras
• Representation theory of semisimple Lie algebras; Lie algebra cohomology
• Quantum groups, Kac-Moody algebras and their representations theory. algebra cohomology.
