Abstract

In this paper we study supersymmetric co-dimension 2 and 4 defects in the compactification of the 6d theory of type on a 3-manifold . The so-called 3d-3d correspondence is a relation between complexified Chern-Simons theory (with gauge group ) on and a 3d theory . We establish a dictionary for this correspondence in the presence of supersymmetric defects, which are knots/links inside the 3-manifold. Our study employs a number of different methods: state-integral models for complex Chern-Simons theory, cluster algebra techniques, domain wall theory , 5d SYM, and also supergravity analysis through holography. These methods are complementary and we find agreement between them. In some cases the results lead to highly non-trivial predictions on the partition function. Our discussion includes a general expression for the cluster partition function, in particular for non-maximal punctures and . We also highlight the non-Abelian description of the 3d theory with defect included, as well as its Higgsing prescription and the resulting `refinement' in complex CS theory. This paper is a companion to our shorter paper arXiv:1510.03884, which summarizes our main results.
