Such a general criterion provides representing measures with support contained in the space of characters of $A$ whose restrictions to $V$ are $q-$continuous. This allows us in turn to prove existence results for the case when $V$ is endowed with a nuclear topology. In particular, we apply our findings to the symmetric tensor algebra of a nuclear space.", "revisions": [ { "version": "v1", "updated": "2023-01-30T14:45:31.000Z" } ], "analyses": { "subjects": [ "44A60", "46M40", "28C20" ], "keywords": [ "nuclear space", "moment problem", "symmetric tensor algebra", "unital commutative real algebra", "representing radon measure" ], "note": { "typesetting": "TeX", "pages": 30, "language": "en", "license": "arXiv", "status": "editable" } } }
