An operator $A$ on on the space of tempered distributions $\\mathcal{S}^\\prime$ is regular if $u$ belongs to the Schwartz class $\\mathcal S$ whenever $Au\\in \\mathcal S$. By using tensor products of topological vector spaces and a kind of Wigner transform we reduce the study of regularity of a non hypo-elliptic differential operator, like the twisted laplacian, to a hypo-elliptic one, like the harmonic oscillator.", "revisions": [ { "version": "v1", "updated": "2012-06-15T13:14:40.000Z" } ], "analyses": { "subjects": [ "35H99" ], "keywords": [ "regularity", "non hypo-elliptic partial differential equations", "non hypo-elliptic differential operator", "schwartz class", "tensor products" ], "note": { "typesetting": "TeX", "pages": 9, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2012arXiv1206.3455B" } } }
