Thereby, we give a unified treatment of the determinations of the space of traces (i) on PsiDOs of noninteger orders or of regular parity-class, (ii) on integer order PsiDOs, (iii) on nonpositive order PsiDOs in dimension greather than or equal to 2, and (iv) on nonpositive order PsiDOs in dimension 1.", "revisions": [ { "version": "v2", "updated": "2008-01-08T03:40:26.000Z" } ], "analyses": { "subjects": [ "58J40", "58J42" ], "keywords": [ "pseudodifferential operators", "nonpositive order psidos", "commutators", "integer order psidos", "regular parity-class" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 22, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2007arXiv0707.4265P" } } }
