description: Operator theory is a significant part of many important areas of modern functional analysis differential equations index theory representation theory mathematical physics and more. This text covers the central themes of operator theory presented with the excellent clarity and style that readers have come to associate with Conway's writing. Early chapters introduce and review material on C*-algebras normal operators compact operators and non-normal operators. The topics include the spectral theorem the functional calculus and the Fredholm index. Also some deep connections between operator theory and analytic functions are presented. Later chapters cover more advanced topics such as representations of C*-algebras compact perturbations and von Neumann algebras. Major results such as the Sz.-Nagy Dilation Theorem the Weyl-von Neumann-Berg Theorem and the classification of von Neumann algebras are covered as is a treatment of Fredholm theory. These advanced topics are at the heart of current research. The last chapter gives an introduction to reflexive subspaces i.e. subspaces of operators that are determined by their invariant subspaces. These along with hyperreflexive spaces are one of the more successful episodes in the modern study of asymmetric algebras. Professor Conway's authoritative treatment makes this a compelling and rigorous course text suitable for graduate students who have had a standard course in functional analysis.
