Query: Instanton moduli spaces and $\mathscr W$-algebras   We describe the (equivariant) intersection cohomology of certain moduli
spaces ("framed Uhlenbeck spaces") together with some structures on them (such
as e.g.\ the Poincar\'e pairing) in terms of representation theory of some
vertex operator algebras ("$\mathscr W$-algebras").
