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…
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 o…
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 …
Twisted Holography and Celestial Holography from Boundary Chiral Algebra
Keyou Zeng
We study the Kaluza-Klein reduction of various holomorphic theories. The KK reduction is analyzed in the BV formalism, resulting in theories that come from the holomorphic top…
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…
Monopole Operators and Bulk-Boundary Relation in Holomorphic Topological Theories
Keyou Zeng
We study the holomorphic twist of 3d N = 2 supersymmetric field theories, discuss the perturbative bulk local operators in general, and explicitly construct non perturbative bulk l…
Homotopy Algebras in Higher Spin Theory
Si Li, Keyou Zeng
Motivated by string field theory, we explore various algebraic aspects of higher spin theory and Vasiliev equation in terms of homotopy algebras. We present a systematic study of u…
A construction of quarter BPS coherent states and Brauer algebras
Hai Lin, Keyou Zeng
BPS coherent states closely resemble semiclassical states and they have gravity dual descriptions in terms of semiclassical geometries. The half BPS coherent states have been well…
Detecting topology change via correlations and entanglement from gauge/gravity correspondence
Hai Lin, Keyou Zeng
We compute a momentum space version of the entanglement spectrum and entanglement entropy of general Young tableau states, and one-point functions on Young tableau states. These ph…
