Factorization Algebras and Quantum Groups from Generalized Poisson Sigma Models
Keyou Zeng
In this work we introduce and study a family of holomorphic--topological field theories, which we call generalized Poisson sigma models. These theories are higher-dimensional analo…

Large Vertex Algebras via Deligne Category
Keyou Zeng
In this paper, we propose a new construction of vertex algebras using the Deligne category. This approach provides a rigorous framework for defining the so-called large vertex…

Poisson Vertex Algebras and Three-Dimensional Gauge Theory
Ahsan Z. Khan, Keyou Zeng
We introduce a mixed holomorphic-topological gauge theory in three dimensions associated to a (freely generated) Poisson vertex algebra. The -bracket of the PVA plays the role…
