abstract

In this paper, we present a geometric description of foams, which are prevalent in topological quantum field theories (TQFTs) based on quantum algebra, and reciprocally explore the geometry of Rozansky-Witten (RW) theory from an algebraic perspective. This approach illuminates various aspects of decorated TQFTs via geometry of the target space $X$ of RW theory. Through the formulation of the Knizhnik-Zamolodchikov (KZ) equation within this geometric framework, we derive the corresponding braiding and associator morphisms. We discuss applications where the target space of RW theory emerges as the Coulomb branch of a compactified 6d SCFT or Little String Theory, with the latter being particularly intriguing as it results in a compact $X$.

  1. Irregular KZ equations and Kac-Moody representations

    hep-th 2024-12 conditional novelty 6.0 of 10

    Irregular Kac-Moody representations produce irregular KZ equations, and derivatives of irregular Liouville conformal blocks with screening charges satisfy these equations.

  2. Non-invertible twisted compactification of class $\mathcal S$ theory and $(B,B,B)$ branes

    hep-th 2024-12 conditional novelty 6.0 of 10

    Non-invertible twisted compactification of class S theories on S^1 produces 3d N=4 sigma models whose target spaces are fixed-point sets of mapping class group actions on Hitchin moduli space, i.e. (B,B,B) branes.
