Yangians and cohomological Hall algebras of Higgs sheaves on curves
Speaker(s): Olivier Schiffmann
Abstract: We 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 P^1, and relate its COHA to the affine Yangian of sl_2.
