DESCRIPTION:Speaker: Junliang Shen\nhosted by Tamas Hausel\nAbstract: The t
 opology of the Hitchin fibrations plays crucial role in geometry\, math ph
 ysics\, and representation theory. In this talk\, we will discuss two ques
 tions arised naturally in the study of Hitchin fibrations in view of the P
 =W conjecture: (a) How to locate the tautological classes in the perverse 
 filtration? (b) Is the perverse filtration multiplicative for Hitchin fibr
 ations? I will explain how connnections to the geometry of some special a
 lgebraic varieties (Hilbert schemes\, abelian surfaces\, hyper-Kahler mani
 folds)  lead to progress to answering these questions. Based on joint wor
 k with Mark de Cataldo\, Davesh Maulik\, Qizheng Yin\, Zili Zhang.
