A large variety of topics are covered, including single operator theory, $$C^*$$-algebras, spectral theory, special classes of concrete operators, and holomorphic operator functions. The book also includes applications in other areas of mathematics and science. A publication of the Theta Foundation. Distributed worldwide, except in Romania, by the AMS. Readership Graduate students and research mathematicians interested in operator theory and its applications. Table of Contents J. Agler and J. E.
