Approximation by multivariate Kantorovich-Kotelnikov operators

Classical Analysis and ODEs 2018-11-20 v1

Abstract

Approximation properties of multivariate Kantorovich-Kotelnikov type operators generated by different band-limited functions are studied. In particular, a wide class of functions with discontinuous Fourier transform is considered. The LpL_p-rate of convergence for these operators is given in terms of the classical moduli of smoothness. Several examples of the Kantorovich-Kotelnikov operators generated by the sinc{\rm sinc}-function and its linear combinations are provided.
