Raviolo Vertex Algebras, Cochains, and Conformal Blocks

Abstract Raviolo vertex algebras were introduced recently by Garner and Williams in [25]. Working at the level of cochain complexes, in the present paper we construct spaces of conformal blocks, or more precisely their duals, coinvariants, in the raviolo setting. We prove that the raviolo state-field map correctly captures the limiting behaviour of coinvariants as marked points collide.
