Approximation of Functions: Theory and Numerical Methods

for example, the so-called Lp approximation, the Bernstein approxima­ tion problem (approximation on the real line by certain entire functions), and the highly interesting studies of J. L. WALSH on approximation in the complex plane. I would like to extend sincere thanks to Professor L. COLLATZ for his many encouragements for the writing of this book. Thanks are equally due to Springer-Verlag for ...
