Title: Generalized Weyl Algebras, Birational Equivalences and Gelfand-Kirillov Conjecture

Abstract: Rank 1 generalized Weyl algebras (GWAs) form an interesting class of algebras that include (quantum) enveloping algebra of sl(2) and some interesting quantum groups of rank 1 and 2. In this talk I will define GWAs and then explain how these examples fit into the framework of GWAs. Birational equivalence, on the other hand, is a tool (commutative) algebraic geometers use quite extensively. Interestingly, GWAs are birationally equivalent to a smash product with a torus of rank-1. Time permitting, I will talk about how all of these relate to Gelfand-Kirillov conjecture.
