Kazhdan-Lusztig Correspondence for Vertex Operator Superalgebras from Abelian Gauge Theories
Thomas Creutzig, Wenjun Niu
We prove the Kazhdan-Lusztig correspondence for a class of vertex operator superalgebras which, via the work of Costello-Gaiotto, arise as boundary VOAs of topological B twist of 3…

Line Operators in 3d Holomorphic QFT: Meromorphic Tensor Categories and dg-Shifted Yangians
Tudor Dimofte, Wenjun Niu, Victor Py
We study line operators and their OPE's in perturbative 3d holomorphic-topological QFT's, including holomorphic-topological twists (quarter-BPS sectors) of 3d theories. In pa…

1-shifted Lie bialgebras and their quantizations
Wenjun Niu, Victor Py
In this paper, we define (cohomologically) 1-shifted Manin triples and 1-shifted Lie bialgebras, and study their properties. We derive many results that are parallel to those found…
