Hermite-type interpolation in terms of exponential polynomials

Classical Analysis and ODEs 2024-12-12 v1

Abstract

Motivated by classical results of approximation theory, we define an Hermite-type interpolation in terms of nn-dimensional subspaces of the space of nn times continuously differentiable functions. In the main result of this paper, we establish an error term in integral form for this interpolation in the case when the nn-dimensional subspace is the kernel of an nnth order linear differential operator with constant coefficients. Several corollaries are deduced illustrating the applicability of this result.
