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.
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 dif
