Cohomological Hall algebras associated to curves

By Olivier Schiffmann

Appears in collection : Higher Structures in Holomorphic and Topological Field Theory

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.
