Masoud Kamgarpour (Queensland) is giving a representation theory seminar on Wednesday 4-5pm, in Carslaw 830. Title: Hitchin System and ramifications Abstract: The Hitchin system is a remarkable mathematical object sitting at the crossroad between geometry, representation, number theory, and physics. The first half of the talk will be a general introduction to this area of mathematics. In the second half, I will discuss some recent advances in understanding what happens to the Hitchin system if one allows for âramificationâ at finitely many points.
