Approximation with Quasi-Splines

by G.H Kirov

Overview

In the theory of splines, a function is approximated piece-wise by (usually cubic) polynomials. Quasi-splines is the natural extension of this, allowing us to use any useful class of functions adapted to the problem.
Approximation with Quasi-Splines is a detailed account of this highly useful technique in numerical analysis.

The book presents the requisite approximation theorems and optimization methods, developing a unified theory of one and several variables. The author applies his techniques to the evaluation of definite integrals (quadrature) and its many-variables generalization, which he calls "cubature."

This book should be required reading for all practitioners of the methods of approximation, including researchers, teachers, and students in applied, numerical and computational mathematics.

Editorial Reviews

In numerical analysis, quasi-splines is an extension of the theory of splines in which any useful class of functions (not just polynomials) can be used to piece-wise approximate other functions. May be used as a text for a second course in numerical analysis. The author is from the Plovdiv Higher Institute of Food and Flavour Industries, Bulgaria. Annotation c.
