We introduce the notion of meromorphic tensor category and illustrate it in several examples. They include representations of quantum affine algebras, chiral algebras of Beilinson and Drinfeld, G-vertex algebras of Borcherds, and representations of GL over a local field. Hopefully the formalism will accomodate various tensor structures arising in relation to the quantized Knizhnik-Zamolodchikov equations and deformed CFT

  1. Line Operators in 3d Holomorphic QFT: Meromorphic Tensor Categories and dg-Shifted Yangians

    hep-th 2025-08 conditional novelty 7.0 of 10

    In 3d holomorphic-topological QFTs, line operators and their OPEs are controlled by a Koszul-dual A-infinity algebra carrying a dg-shifted Yangian structure with a degree-1 r-matrix.

  2. Conformal blocks, parenthesized braid operad, and $c=1/2$ Virasoro vertex operator algebra

    math.QA 2026-06 unverdicted novelty 5.0 of 10

    Computes four-point conformal blocks for the c=1/2 Virasoro VOA using hypergeometric functions and identifies its module category with the Tambara-Yamagami category over Z2 via analytic continuation of blocks.
