Each vector in this Hilbert space is described by a (rectangular) surface in $\\mathbb{R}^4$, for which a vector field is defined on it. The inner product on this Hilbert space is defined via a surface integral, which is associated with the area of the surface.", "revisions": [ { "version": "v2", "updated": "2023-06-22T01:04:12.000Z" } ], "analyses": { "subjects": [ "22E43" ], "keywords": [ "unitary representation", "inhomogeneous", "surface integral", "inner product", "vector field" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
