Abstract: Let be the coordinate ring of a smooth affine curve over an algebraically closed field of characteristic zero . For a subalgebra of with integral closure denote by the ring of differential operators on and by the finite-dimensional factor of by its unique minimal ideal. The theory of diagonal -subspace systems is introduced. This is used to show that if is a finite-dimensional -algebra and is any integer there exists such an with
