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…

$L_{1} (psl_{n ∣ n})$ from BRST reductions, associated varieties and nilpotent orbits

Andrea E. V. Ferrari, Aiden Suter

We verify a conjecture of Beem and the first author stating that a certain family of physically motivated BRST reductions of beta-gamma systems and free fermions is isomorphic to $…
