Chiral Extensions of Cotangent Yangian
Keyou Zeng
We construct chiral extensions of the cotangent Yangian using vertex algebroids. At zero level, the construction yields a vertex algebra with a compatible coproduct, whose Zhu redu…
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…
Loday-Quillen-Tsygan theorem on Quivers
Keyou Zeng
The well-known Loday-Quillen-Tsygan theorem calculates the Lie algebra homology of the infinite general linear Lie algebra over an unital associative algebra …
Quadratic Duality for Chiral Algebras
Zhengping Gui, Si Li, Keyou Zeng
We introduce a notion of quadratic duality for chiral algebras. This can be viewed as a chiral version of the usual quadratic duality for quadratic associative algebras. We study t…
