Given the existence of a measure $\\mu$ representing a linear functional $L: S(V)\\to\\mathbb{R}$, we deduce a sufficient determinacy condition on $L$ provided that the support of $\\mu$ is contained in a countable union of some topological duals of $V$. We will compare this result with some already known in literature for such a general form of the moment problem and further discuss how some prior knowledge on the support of the representing measure influences its determinacy.", "revisions": [ { "version": "v1", "updated": "2016-03-24T20:44:58.000Z" } ], "analyses": { "subjects": [ "44A60" ], "keywords": [ "locally convex space", "moment problem", "symmetric algebra", "sufficient determinacy condition", "linear functional" ], "note": { "typesetting": "TeX", "pages": 7, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2016arXiv160307747I" } } }
