DESCRIPTION:Title: <a href="https://researchseminars.org/talk/MITLie/28/">
 Hitchin fibration and commuting schemes</a>\nby Tsao-Hsien Chen (Universit
 y of Minnesota) as part of MIT Lie groups seminar\n\nLecture held in 2-142
 .\n\nAbstract\nThe commuting scheme has always been of great interest in i
 nvariant theory but it was only recent that it appears as a primordial obj
 ect in the study of the Hitchin fibration for higher dimensional varieties
 . I will explain how the invariant theory for the commuting scheme\, in pa
 rticular the Chevalley restriction theorem for the commuting scheme\, is u
 sed in the study of Hitchin fibration and the proof of the Chevalley restr
 iction theorem in the case of symplectic Lie algebras. The talk is based o
 n joint work with Ngo Bao Chau.\n
