Finite dimensional Hopf actions on deformation quantizations
We study when a finite dimensional Hopf action on a quantum formal deformation A of a commutative domain A 0 (i.e., a deformation quantization) must factor through a group algebra. In particular, we show that this occurs when the Poisson center of the fraction field of A 0 is trivial.
