Helson's Harmonic Analysis

The second edition of Harmonic Analysis by Henry Helson is being published in paperback by Hindustan Book Agency in their TRIM series.

The book is enlarged and considerably rewritten in comparison with the first edition. Among the new topics are: infinite product spaces with applications to probability, disintegration of measures on product spaces, positive definite functions on the line, and additional information about Weyl’s theorems on equidistribution. Topics that have continued from the first edition include Minkowski’s theorem, measures with bounded powers, idempotent measures, spectral sets of bounded functions and a theorem of Szegö, and the Wiener Tauberian theorem.

The book comes with a statutory warning: Readers of the book should have studied the Lebesgue integral, the elementary theory of analytic and harmonic functions, and the basic theory of Banach spaces. The treatment is classical and as simple as possible. This is an instructional book, not a treatise.

The review in the Bulletin of the American Mathematical Society says "...this volume can be an excellent way to get one's feet wet and see whether it is worthwhile to take the plunge. The book has helpful and challenging exercises for the reader. It should be emphasized that the great strength of the book lies in the large number of interesting special results it contains. Many of the prettiest facts of harmonic analysis are on display here in a very attractive setting"
