Poisson Vertex Algebra of Seiberg-Witten Theory
Ahsan Z. Khan
The space of local operators in the -cohomology of the holomorphic-topological supercharge in a four-dimensional theory carries the structure of a Poisson 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…

On the Algebra of the Infrared with Twisted Masses
Ahsan Z. Khan, Gregory W. Moore
The Algebra of the Infrared \cite{Gaiotto:2015aoa} is a framework to construct local observables, interfaces, and categories of supersymmetric boundary conditions of massive $\math…
