These results hold over a smooth manifold endowed with a flat projective structure. As an application, we classify the Vect(M)-equivariant maps from $D_p$ to $D_q$ over any manifold M, recovering and improving earlier results by N. Poncin. This provides the complete answer to a question raised by P. Lecomte about the extension of a certain intrinsic homotopy operator.", "revisions": [ { "version": "v1", "updated": "2002-06-20T13:25:30.000Z" } ], "analyses": { "subjects": [ "17B66", "16S32" ], "keywords": [ "equivariant symbol calculus", "differential operators acting", "intrinsic homotopy operator", "projectively equivariant symbol map", "differential operators transforming p-forms" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 14, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2002math......6213B" } } }
