Vertex algebras and 4manifold invariants
Abstract
We propose a way of computing 4manifold invariants, old and new, as chiral correlation functions in halftwisted 2d $\mathcal{N}=(0,2)$ theories that arise from compactification of fivebranes. Such formulation gives a new interpretation of some known statements about SeibergWitten invariants, such as the basic class condition, and gives a prediction for structural properties of the multimonopole invariants and their nonabelian generalizations.
