To obtain this, type 1,1-operators are extended to distributions with compact spectrum, and Fourier transformed operators of this type are on such distributions proved to satisfy a support rule, generalising the rule for convolutions. Thereby the use of reduced symbols, as introduced by Coifman and Meyer, is replaced by direct application of the paradifferential methods. A few flaws in the literature have been detected and corrected.", "revisions": [ { "version": "v1", "updated": "2017-02-03T16:18:15.000Z" } ], "analyses": { "subjects": [ "47G30", "46E35" ], "keywords": [ "pseudo-differential operator", "triebel-lizorkin space", "main result", "triebel-lizorkin framework", "paradifferential methods" ], "tags": [ "journal article" ], "publication": { "publisher": "Hindawi", "journal": "Adv.
