Query: Cohomological Hall algebras and vertex algebras   The moduli stack of representations of a quiver, or coherent sheaves on a
proper curve, carries two structures on its cohomology: a Hall algebra and
braided vertex coalgebra. We show that they are compatible, by developing a
formulation of abelian localisation which works in the derived/singular
setting. An application of these techniques gives an explicit formula for the
cohomological Hall algebra products.
