Konvexe Zerlegung von Differenzenquotienten mit Anwendung auf die Splineinterpolation, Zerlegungen von verallgemeinerten Differenzenquotienten bilden ein Hilfsmittel, zu einer stabilen L?sung der Interpolationsaufgabe zu gelangen. Diese Methode führt auch bei nichtlinearen Splinefunktionen zu einem Algorithmus.

As E. doesn’t fullfill the Haar-condition, the uniqueness could only be verified for sum of exponentials with nonnegative coefficients. Nevertheless this part of E., the family .is of some relevance in practice, which is documented by the closing numerical example.

Simultaneous Interpolation and Approximation by Entire Functions of Exponential Type,ct interval, by polynomials, has been extensively studied by Runge, Bernstein, Faber, Fejér, Turán and others. Given a continuous function f on [?1,1] what is more natural than to think that a sequence of polynomials {p. (f;?)} which duplicate the function at n+1 equally spaced points of the interval will converge uniformly to f as n→∞.

The purpose of this paper is to extend this interpolation property to a class of analytic, not necessarily entire functions, which includes (z?a)., ln(z?a) (∣a∣ > 1, m∈N).

In fact, evidence exists that as tariffs are lowered in international forums such as the Kennedy Round, industrial nations are turning more heavily to nontariff barriers to insulate domestic producers from foreign competition.
