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…

Holomorphic Surface Defects in Four-Dimensional Chern-Simons Theory
Ahsan Z. Khan
We derive the framing anomaly of four-dimensional holomorphic-topological Chern-Simons theory formulated on the product of a topological surface and the complex plane. We show that…

Categorical Wall-Crossing in Landau-Ginzburg Models
Ahsan Z. Khan, Gregory W. Moore
We describe how categorical BPS data including chain complexes of solitons, CPT pairings, and interior amplitudes jump across a wall of marginal stability in two-dimensional $\math…
