Abstract
In this dissertation, we investigate the 3d3d correspondence for Seifert manifolds. This correspondence, originating from string theory and Mtheory, relates the dynamics of threedimensional quantum field theories with the geometry of threemanifolds.
We first start in Chapter II with the simplest cases and demonstrate the extremely rich interplay between geometry and physics even when the manifold is just a direct product. In this particular case, by examining the problem from various vantage points, we generalize the celebrated relations between 1) the Verlinde algebra, 2) quantum cohomology of the Grassmannian, 3) quantization of ChernSimons theory and 4) the index theory of the moduli space of flat connections to a completely new set of relations between 1) the "equivariant Verlinde algebra" for a complex group, 2) the equivariant quantum Ktheory of the vortex moduli space, 3) quantization of complex ChernSimons theory and 4) the equivariant index theory of the moduli space of Higgs bundles.
In Chapter III we move one step up in complexity by looking at the next simplest threemanifoldslens spaces. We test the 3d3d correspondence for theories that are labeled by lens spaces, reaching a full agreement between the index of the 3d N=2 "lens space theory" and the partition function of complex ChernSimons theory on the lens space.
The two different types of manifolds studied in the previous two chapters also have interesting interactions. We show in Chapter IV the equivalence between two seemingly distinct 2d TQFTs: one comes from the "Coulomb branch index" of the class S theory on a lens space, the other is the "equivariant Verlinde formula". We check this relation explicitly for SU(2) and demonstrate that the SU(N) equivariant Verlinde algebra can be derived using field theory via (generalized) ArgyresSeiberg dualities.
In the last chapter, we directly jump to the most general situation, giving a proposal for the 3d3d correspondence for an arbitrary Seifert manifold. We remark on the huge class of novel dualities relating different descriptions of the "Seifert theory" associated with the same Seifert manifold and suggest ways that our proposal could be tested.
