Deformation quantization with traces

Abstract
 In this Letter we prove a statement closely related to the cyclic formality conjecture. In particular, we prove that for a constant volume form Ω and a Poisson bivector field π on R d such that divΩπ=0, the Kontsevich star product with the harmonic angle function is cyclic, i.e. ∫Rd (f*g)·h·Ω=∫ ∫Rd (g*h)·f·Ω for any three functions f,g,h on Rd (for which the integrals make sense). We also prove a globalization of this theorem in the case of arbitrary Poisson manifolds and an arbitrary volume form, and prove a generalization of the ConnesFlatoSternheimer conjecture on closed star products in the Poisson case.
