We will establish conditions which ensure that the set of values is dense. Our methods involve homogeneous dynamics and we will prove a orbit closure classification type result in this setting. This result has additional applications. In particular, we use it to study the set of integral values of a system consisting of a quadratic form and several linear forms.", "revisions": [ { "version": "v1", "updated": "2017-11-01T15:59:25.000Z" } ], "analyses": { "keywords": [ "quadratic form", "related problem", "orbit closure classification type result", "quasicrystals", "linear forms" ], "note": { "typesetting": "TeX", "pages": 18, "language": "en", "license": "arXiv", "status": "editable" } } }
