Abstract

In the present paper we will introduce a new approach to multivariate interpolation by employing polyharmonic functions as interpolants, i.e. by solutions of higher order elliptic equations. We assume that the data arise from CC^{\infty} or analytic functions in the ball BR.B_{R}. We prove two main results on the interpolation of CC^{\infty} or analytic functions ff in the ball BRB_{R} by polyharmonic functions hh of a given order of polyharmonicity p.p.
