Abstract: We generalize Chevalley's theorem about restriction to the case when a semisimple Lie algebra is replaced by a quantum group and the target space of the polynomial maps is replaced by a finite dimensional representation of this quantum group. We prove that the restriction map is injective and describe the image.
