Vertex Superalgebras for Hypertoric Varieties and 3d Abelian Gauge Theories

Tomoyuki Arakawa, Andrea E. V. Ferrari, Sven MÃ¶ller

Hypertoric (or toric hyperkÃ¤hler) varieties are a class of symplectic singularities and their resolutions, obtained as Hamiltonian reductions of a symplectic vector space acted on…

Remarks on Associated Varieties and Minimal Tension Holography

Andrea E. V. Ferrari

We comment on certain analogies that have recently emerged between path integral localisation phenomena in minimal tension string theory on $AdS_{3} \times S^{3} \times T^{4}$ and…

Free field realisation of boundary vertex algebras for Abelian gauge theories in three dimensions

Christopher Beem, Andrea E. V. Ferrari

We study the boundary vertex algebras of $A$ -twisted $N = 4$ Abelian gauge theories in three dimensions. These are identified with the BRST quotient (semi-infinite cohomolo…

3d $N = 4$ Mirror Symmetry, TQFTs, and 't Hooft Anomaly Matching

Mahesh K. N. Balasubramanian, Anindya Banerjee, Matthew Buican +3

Any local unitary 3d $N = 4$ superconformal field theory (SCFT) has a corresponding "universal" relevant deformation that takes it to a gapped phase. This deformation prese…
