This edition of Bounded Analytic Functions is the same as the first edition (Academic Press, New York, 1981) except for the correction of several mathematical and typographical errors. The book contains information about Hardy spaces, conjugate functions, bounded mean oscillation and duality, interpolating sequences, corona construction, Douglas algebras and many other topics. The reader is supposed to have a background in complex analysis and function algebras. The author has selected a wide range of beautiful topics and some of them are very deep. This book is not intended as a starting place for the novice but it is a gold mine for researchers and experts.
