Query: Formality of Cyclic Chains   We prove a conjecture raised by Tsygan, namely the existence of an
L-infinity-quasiisomorphism of L-infinity-modules between the cyclic chain
complex of smooth functions on a manifold and the differential forms on that
manifold. Concretely, we prove that the obvious u-linear extension of
Shoikhet's morphism of Hochschild chains solves Tsygan's conjecture.
