If you have a question about this talk, please contact nobody. EMGW05 - Moduli stacks and enumerative geometry Chern classes of universal families have played a crucial role in the study of cohomology of the moduli of stable vector bundles on Riemann surfaces since the work of Mumford and Atiyah-Bott over 40 years ago. In recent years, the study of cohomological aspects of non-abelian Hodge theory (the P=W conjecture) and enumerative geometry (Gopakumar-Vafa theory) links Chern classes to a very different structure—- the perverse filtration for certain moduli of sheaves and Higgs bundles. I will first review this phenomenon. Then I will discuss a theory of Fourier transform which explains this link. Based on joint work with Davesh Maulik and Qizheng Yin.
