Familiarity with the structure theory and representation theory of complex semisimple Lie algebras.
Grading: There will be no compulsory homework. Optional exercises and problems will be given during lectures.
Exams: There will be no exams.
Synopsis: This course will be an introduction to the theory of quantum groups, canonical bases, and crystal graphs. Quantum groups, or quantized enveloping algebras, are Hopf algebras that deform the universl enveloping algebra of a complex semisimple Lie algebra. In the first half of the course I will discuss the definition and representation theory of quantum groups. In the second half of the course, I will discuss the "canonical bases" or "global bases". These are distinguished bases for irreducible representations of quantum groups, or for the upper-half of the quantized enveloping algebra. At q = 0, we obtain crystal graphs, which are a combinatorial model for irreducible representations of complex semisimple Lie algebras.
For the first half of the course, my plan is to follow "A guide to Quantum Groups", by Vyjayanthi Chari and Andrew Pressley.
For the second half of the course, I hope to roughly follow "On crystal bases of the q-analogue of universal enveloping algebras" by Masaki Kashiwara (Duke Math. J. 1991).
