In 1909 Alfred Haar introduced into analysis a remarkable system which
bears his name. The Haar system is a complete orthonormal system on
[0,1] and the Fourier-Haar series for arbitrary continuous function
converges uniformly to this function.
This volume is devoted to the investigation of the Haar system from the
operator theory point of view. The main subjects treated are: classical
results on unconditional convergence of the Haar series in modern
presentation; Fourier-Haar coefficients; reproducibility; martingales;
monotone bases in rearrangement invariant spaces; rearrangements and
multipliers with respect to the Haar system; subspaces generated by
subsequences of the Haar system; the criterion of equivalence of the
Haar and Franklin systems.
Audience: This book will be of interest to graduate students and
researchers whose work involves functional analysis and operator theory
