On the semi-infinite cohomology of graded-unitary vertex algebras
Christopher Beem, Niklas Garner
Recently, the first author with A. Ardehali, M. Lemos, and L. Rastelli introduced the notion of graded unitarity for vertex algebras. This generalization of unitarity is motivated…

Higgs and coulomb branches from superconformal raviolo vertex algebras
Niklas Garner, Surya Raghavendran, Brian R. Williams
We propose a method for extracting the Higgs and Coulomb branches of a three-dimensional N = 4 quantum field theory from the algebra of local operators in its holomorphic-topologic…
