Required Text:

Introduction to Lie Algebras and Representation Theory by James Humphreys (Springer, 1972)

to be in the good graces of the instructor
What to Expect:
This is the second course in the Algebraic Structures sequence. I will classify finite-dimensional complex semisimple Lie algebras, also proving some structural results on general Lie algebras along the way. Although one usually first encounters Lie algebras in a manifolds course, the treatment (following the text) will be entirely algebraic. Homework will be collected every other Friday.
