Abstract: Let be the discrete Green's function over a discrete *h*-convex region of the plane; i.e., for for . Assume that and are Hölder continuous over and positive. We show that and , where is an *m*th order difference quotient with respect to the components of *P* or *Q*, and denotes an *m*th order difference quotient only with respect to the components of *P*.
