Differential Geometry Seminar: Jianqing Yu (Chern Institute of Mathematics & UCSB), 'On the Witten rigidity theorem'

Event Date: 

Friday, November 16, 2012 - 3:00pm to 4:00pm

Event Location: 

  • 6635 South Hall

In this talk, I will first explain the basic idea of Witten's loop space construction of elliptic genus. Then I will briefly discuss the proof of Witten's rigidity theorem as well as its family generalizations. At last, I will talk about my joint work with Bo LIU, the Witten rigidity theorem on Z/k manifolds (arxiv 1104.3972) and String^c manifolds (arxiv 1206.5955).
