Cohomological Hall algebras associated to curves
We will define and give some algebraic properties of cohomological Hall algebras of the stacks of coherent, resp. Higgs sheaves on a compacts Riemann surface X. We will in particular show how these are related to the structure of the cohomology rings of the moduli spaces of semistable vector bundles, resp. Higgs bundles on X.
