**Contributions to Fourier Analysis**

by A. Zygmund, et al.

**Publisher**: Princeton University Press 1950**ISBN/ASIN**: 0691079307**Number of pages**: 207

**Description**:

In the theory of convergence and summability, whether for ordinary Fourier series or other expansions, emphasis is placed on the phenomenon of localization whenever such occurs, and in the present paper a certain aspect of this phenomenon will be studied for the problem of best approximation as well.
