This volume deals with main results of the 3rd International Conference on Multivariate Approximation, organized by the University of Dortmund. Special emphasis

Self-contained presentation of multivariate approximation from classical linear approximation to contemporary nonlinear approximation.

This book presents an in-depth study on advances in constructive approximation theory with recent problems on linear positive operators. State-of-the-art resear

Many practical applications require the reconstruction of a multivariate function from discrete, unstructured data. This book gives a self-contained, complete i
