Title: Cohomological Hall algebras associated to Riemann surfaces
Date: Thu, Oct 18, 2018, 15:30 - 17:00
Place: Seminar Room B
Abstract: We will describe two families of algebras naturally associated to the moduli spaces of vector bundles and Higgs bundles on a (compact) Riemann surface respectively. We will state various results and conjectures regarding their structure (generation, isomorphism with some known quantum groups) and their representation theory (action on some other moduli spaces of vector bundles on Riemann surfaces, etc.). This is joint work with F. Sala and E. Vasserot.
