DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GRT-2020/7/"
 >Yangians and cohomological Hall algebras of Higgs sheaves on curves</a>\n
 by Olivier Schiffmann (Université de Paris-Sud ORSAY) as part of Geometri
 c Representation Theory conference\n\n\nAbstract\nWe will review a set of 
 conjectures related to the structure of cohomological Hall algebras (COHA)
  of categories of Higgs sheaves on curves. We then focus on the case of $\
 \mathbb P^1$\, and relate its COHA to the affine Yangian of $\\mathfrak{sl
 }_2$\n
