  A central result here is the computation of the entire cyclic homology of
canonical smooth subalgebras of stable continuous trace C*-algebras having
smooth manifolds M as their spectrum. More precisely, the entire cyclic
homology is shown to be canonically isomorphic to the continuous periodic
cyclic homology for these algebras. By an earlier result of the authors, one
concludes that the entire cyclic homology of the algebra is canonically
isomorphic to the twisted de Rham cohomology of M.
