Multivariate polynomials are a main tool in approximation. The book begins with an introduction to the general theory by presenting the most important facts on multivariate interpolation, quadrature, orthogonal projections and their summation, all treated under a constructive view, and embedded in the theory of positive linear operators. On this background, the book gives the first comprehensive introduction to the recently developped theory of generalized hyperinterpolation. As an application, the book gives a quick introduction to tomography. Several parts of the book are based on rotation...

This volume presents the main results of the 4th International Conference on Multivariate Approximation, which was held at Witten-Bommerholz, September 24-29, 2000. Nineteen selected, peer-reviewed contributions cover recent topics in constructive approximation on varieties, approximation by solutions of partial differential equations, application of Riesz bases and frames, multiwavelets and subdivision. Features and Topics: interpolation and approximation on compact sets, kergin interpolation error asymptotics radial basis functions energy minimizing configurations on the...

Das Buch verfolgt die Entwicklung des Tonsystems seit dem griechischen Altertum in mathematischer Sicht. Themen sind u.a. das Verhaltnis der gleichschwebenden Temperatur zur reinen Stimmung und das Tonartencharakteristiken-Problem. Und warum gibt es eigentlich keine 13-Ton-Musik? Die Obertonreihe der Saite, der verschiedenen Pfeifen, und der Pauke wird aus der Wellengleichung und den jeweiligen Randbedingungen hergeleitet. Den Klang bestimmen die Anfangswerte, und damit der Kunstler. Fur die Pauke sind die Besselfunktionen verantwortlich. Vom Autor berechnete Klangfiguren und...
