We provide an alternative construction of this chiral algebra by performing an $\\Omega$-deformation~of a topological-holomorphic twist of the $\\mathcal{N}=(2,0)$ theory on $\\mathbf{R}^6$ and restricting to the cohomology of a specific supercharge. In addition, we show that the central charge of the chiral algebra can be obtained by performing equivariant integration of the anomaly polynomial of the six-dimensional theory. Furthermore, we generalize this construction to include orbifolds of the $\\mathbf{R}^4$ transverse to the chiral algebra plane.", "revisions": [ { "version": "v1", "updated": "2020-10-05T18:25:57.000Z" } ], "analyses": { "keywords": [ "deformations", "chiral algebra plane", "two-dimensional chiral algebra", "performing equivariant integration", "central charge" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
