โœฆ Synopsis

An estimate due to Gaier [2] for the error committed in replacing a periodic function f by an interpblating trigonometric polynomial is sharpened in such a way that the estimate makes evident the interpolating property of the polynomial. A similar improvement is given for Gaier's estimate of the difference between the conjugate of f and the conjugate trigonometric polynomial.

This paper considers the variational problem of Hermite interpolation and its error bounds. The optimal Hermite interpolant, which minimises the semi-norm of the reproducing kernel Hilbert space C h determined by given r-CPD m function h, is just the h-spline Hermite interpolant.

In this paper we offer the best possible error estimates for discrete Abel-Gontscharoff interpolation. As an application, these error bounds are used to provide tests for the right disfocality as well as disconjugacy for higher order difference equations.
