This volume is the result of extensive research into the foundations of quantum mechanics, and presents a new formulation of quantum theory which resolves many existing problems. The formalism is experimentally motivated and is shown to be consistent with recent foundational approaches to quantum mechanics. It is based on new extensions of the theory of group representations, which are developed and illustrated in the text. This new approach establishes connections with quantum logic, philosophy, and the history of science, allowing a broad range of applications not only in physics, but also in such areas as signal processing and neuroscience. Audience: This book will be of interest to researchers and students. It is recommended as a supplementary textbook for advanced courses in quantum mechanics. A background in quantum mechanics and complex analysis is assumed. Booknews Offers a new mathematical formulation of quantum theory, clarifies a number of discrepancies within the prior formulation, describes new applications to experiments in physics, and extends the realm of application beyond physics to such fields as signal processing and neuroscience. The approach is based on new extensions of the theory of group representations, which are developed and illustrated in the text, and connects quantum theory with quantum logic, philosophy, and the history of science. Assumes a knowledge of basic topology and analysis, some modern abstract algebra, and at least rudimentary quantum mechanics. Annotation c. Book News, Inc., Portland, OR (booknews.com)
