Abstract

This is the second part of a project aimed at formalizing Rozansky-Witten models in the functorial field theory framework. In the first part we constructed a symmetric monoidal (,3)(\infty, 3)-category CRW\mathscr{CRW} of commutative Rozansky-Witten models with the goal of approximating the 33-category of Kapustin and Rozansky. In this paper we extend work of Brunner, Carqueville, Fragkos, and Roggenkamp on the affine Rozansky-Witten models: we exhibit a functor connecting their 22-category of matrix factorizations with the homotopy 22-category of CRW\mathscr{CRW}, and calculate the associated TFTs.
