DESCRIPTION:Speaker: Olivier Schiffmann\nhosted by Tamas Hausel\nAbstract: 
 I will discuss an approach to compute the cohomology ring of the moduli st
 acks of semistable vector bundles on a curve\, using cohomological Hall al
 gebras. In particular\, we describe combinatorially the COHA of coherent s
 heaves on a curve.
