In this book, we have attempted to explain a variety of different techniques and ideas which have contributed to this subject in its course of successive refine

The book presents a combination of two topics: one coming from the theory of approximation of functions and integrals by interpolation and quadrature, respectiv

The author develops the limit relations between the errors of polynomial approximation in weighted metrics and apply them to various problems in approximation t

The field of approximation theory has become so vast that it intersects with every other branch of analysis and plays an increasingly important role in applicat

This book compiles research and surveys devoted to the areas of mathematical analysis, approximation theory, and optimization. Being dedicated to A.-M. Legendre
