This paper is concerned with the cubic spline-on-spline procedure considered by Dolezal and Tewarson [3]. We show that when the knots are equally spaced, with spacing h, then the order of accuracy of the spline-on-spline approximations can be better by one power of h than that predicted by the results of [3]. We also indicate how the cubic spline-on-spline process can be extended to quintic splines. © 1987.

Overconvergence properties of quintic interpolatory splines
Behforooz, G. H.; Papamichael, Nicolas (1988)Let Q be a quintic spline with equi-spaced knots on [a, b] interpolating a given function y at the knots. The parameters which determine Q are used to construct a piecewise defined polynomial P of degree six. It is shown ...

End conditions for interpolatory cubic splines with unequally spaced knots
Behforooz, G. H.; Papamichael, Nicolas (1980)A class of end conditions is derived for cubic spline interpolation at unequally spaced knots. These conditions are in terms of function values at the knots and lead to 0 (h4) convergence uniformly on the interval of ...

Optimal superconvergent one step nodal cubic spline collocation methods
Bialecki, B.; Fairweather, G.; Karageorghis, Andreas (2006)We formulate new optimal (fourth) order one step nodal cubic spline collocation methods for the solution of various elliptic boundary value problems in the unit square. These methods are constructed so that the respective ...
