Free field realisation of boundary vertex algebras for Abelian gauge theories in three dimensions
C Beem, AEV Ferrari - arXiv preprint arXiv:2304.11055, 2023 - arxiv.org
We study the boundary vertex algebras of $ A $-twisted $\mathcal {N}= 4$ Abelian gauge
theories in three dimensions. These are identified with the BRST quotient (semi-infinite …

OF CONICAL SYMPLECTIC RESOLUTIONS Quantizations of conical symplectic resolutions I: local and global structure
The dazzling success of algebraic geometry... has so much reorientated the field that one
particular protagonist has suggested, no doubt with much justification, that enveloping …

Quantizations of conical symplectic resolutions I: local and global structure
We re-examine some topics in representation theory of Lie algebras and Springer theory in
a more general context, viewing the universal enveloping algebra as an example of the …

Intersection cohomology of hypertoric varieties
N Proudfoot, B Webster - arXiv preprint math/0411350, 2004 - arxiv.org
A hypertoric variety is a quaternionic analogue of a toric variety. Just as the topology of toric
varieties is closely related to the combinatorics of polytopes, the topology of hypertoric …

A Superconformal Index for HyperK\"{a} hler Cones
AE Barns-Graham, N Dorey - arXiv preprint arXiv:1812.04565, 2018 - arxiv.org
We define an index for $\mathfrak {osp}(4^{*}| 4) $ superconformal quantum mechanics on a
hyperK\"{a} hler cone. The index is defined on an equivariant symplectic resolution of the …
