... deformation quantization of the Poisson structure on N inducedfrom ω. By examining the proof in [Sch] (or in [Sch1] and [Sch2]) of thistheorem, one observes that for continuous families of functions, ... clear that the action of Γleaves the isomorphism class of (L, ∇) invariant, thus alone from this one canconclude that a central extension of Γ acts on (L, ∇) covering the Γ action on M. This is ... group Γ of Σ on Vkcovering its action on T , which preserves the flat connection in P(Vk), we get for each k a finitedimensional projective representation, say ρn,dk, of Γ, namely on the...
