Abstract: Let G be a connected reductive group over an algebraically closed field K ofcharacteristic 0, X an affine symplectic variety equipped with a Hamiltonianaction of G. Further, let * be a G-invariant Fedosov star-product on X suchthat the Hamiltonian action is quantized. We establish an isomorphism betweenthe center of the associative algebra KXh^G and the algebra of formalpower series with coefficients in the Poisson center of KX^G.
