W-algebras of the Deligne-CvitanoviÄ Exceptional series and the minimal 3d SCFT
Thomas Creutzig, Niklas Garner, Byeonggi Go +1
We propose a three-dimensional field theory construction that realizes the vertex algebras associated with the intermediate Lie algebras and the related -cofinite minimal -…

Unravelling the Holomorphic Twist II: Anomalies and Extended Supersymmetry
Pieter Bomans, Niklas Garner, Brian R. Williams +1
Twists of four-dimensional supersymmetric quantum field theories (SQFTs) isolate protected sectors with rich algebraic structures. We develop a unified framework for analyzing symm…

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…
