We characterize Kasparov's K-theory group $\\hat{K}_0(A)$ in terms of graded *-homomorphisms by proving a general converse to the functional calculus theorem for self-adjoint regular operators on graded Hilbert modules. An application to the index theory of elliptic differential operators on smooth closed manifolds and asymptotic morphisms is discussed.", "revisions": [ { "version": "v2", "updated": "2002-03-28T19:53:03.000Z" } ], "analyses": { "keywords": [ "elliptic operators", "graded k-theory", "characterize kasparovs k-theory group", "self-adjoint regular operators", "functional calculus theorem" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 14, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "1999math......6106T" } } }
