This course is a one-semester introduction to Lie groups and
their Lie algebras. In addition, I will devote some time to algebraic
groups and Hopf algebras, in preparation for Reshetikhin's covering
quantum groups in 261B in the Spring.
Prerequisites: Background in algebra and topology equivalent to
202A and 250A. Although 214 (Differential Manifolds) is the official
prerequisite, I will review in the lectures those bits of differential
geometry that we will need.
