CARDINAL INTERPOLATION WITH DIFFERENCES OF TEMPERED FUNCTIONS Academic Article uri icon

abstract

  • In this paper, we investigate the existence and uniqueness of cardinal interpolants associated with functions arising from the kth order iterated discrete Laplacian {down triangle, open}k applied to certain radial basis functions. In particular, we concentrate on determining, for a given radial function , which functions {down triangle, open}k give rise to cardinal interpolation operators which are both bounded and invertible 2 (Z3). In addition to solving the cardinal interpolation problem (CIP) associated with such functions {down triangle, open}k, our approach provides a unified framework and simpler proofs for the CIP associated with polyharmonic splines and Hardy multiquadrics. 1992.
