Kashin, B. S.; Saakyan, A. A. Orthogonal series. (Ортогональные ряды.) (Russian) Zbl 0632.42017 Moskva: Nauka. 496 p. R. 4.10 (1984). Annotation: Fundamental methods in the theory of orthogonal series are presented. Orthonormal systems of general type and important concrete systems are studied (for example, the Haar and Franklin systems). Classical results as well as the achievements of the last years are deduced. All propositions, which fall outside the framework of a university course, are presented with full proofs. The book is written for specialists in mathematical analysis and for post graduate students of the corresponding subjects.
