Exact Schur index in closed form

The superconformal index encodes important information about the protected spectrum of a theory (SCFT), with special case Schur Index counting objects enhanced supersymmetry. authors provide for first time an explicit formula this large class SCFTs by integrating numerous (almost) elliptical integrals. This allows them to several applications like computation non-Lagrangian theories through dualities, properties Vertex Operator Algebras, etc.
