Asymptotically Optimal Approximation and Numerical Solutions of Differential Equations

M.D. Buhmann, Ch.A. Micchelli and A. Ron

Abstract: An optimal finite difference method for the numerical solution of the Cauchy problem for a given partial differential equation is, by definition, the scheme that minimises the local truncation error after one step. In this paper we conduct a study of certain extremal problems that are closely related to optimal finite difference schemes for finding numerical solutions of such problems.
