This book contains a detailed exposition of Carleson-Hunt theorem
following the proof of Carleson: to this day this is the only one giving
better bounds. It points out the motivation of every step in the proof.
Thus the Carleson-Hunt theorem becomes accessible to any analyst.The
book also contains the first detailed exposition of the fine results of
Hunt, Sjölin, Soria, etc on the convergence of Fourier Series. Its final
chapters present original material. With both Fefferman's proof and the
recent one of Lacey and Thiele in print, it becomes more important than
ever to understand and compare these two related proofs with that of
Carleson and Hunt. These alternative proofs do not yield all the results
of the Carleson-Hunt proof. The intention of this monograph is to make
Carleson's proof accessible to a wider audience, and to explain its
consequences for the pointwise convergence of Fourier series for
functions in spaces near $äcal Lü^1$, filling a well-known gap in the
literature.
