DESCRIPTION:Speaker: Du Pei\nhosted by Tamas Hausel\nAbstract: Embedding a 
 mathematical problems into string theory usually enables us to gain new in
 sights into it. In this talk\, I will study the moduli space of wild Hitch
 in systems and its quantization via physics. Although these moduli spaces 
 are non-compact and lead to infinite-dimensional Hilbert spaces after the 
 quantization\, in many cases a C* "Hitchin action" exists\, enabling us to
  talk about the "Hitchin character" of the Hilbert space. This quantity ca
 n be computed using quantum field theory techniques and encodes much geome
 tric and topological information about the moduli space. A surprising rela
 tion to chiral algebras appears once the Hitchin character is decomposed i
 nto a summation over fixed points of the C*-action. This talk is based on 
 joint work with Laura Fredrickson\, Wenbin Yan and Ke Ye.
