Buch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Algebras of bounded operators are familiar, either as C\*-algebras or as von Neumann algebras. A first generalization is the notion of algebras of unbounded operators (O\*-algebras), mostly developed by the Leipzig school and in Japan (for a review, we refer to the monographs of K. Schmüdgen [1990] and A. Inoue [1998]). This volume goes one step further, by considering systematically partial \*-algebras of unbounded operators (partial O\*-algebras) and the underlying algebraic structure, namely, partial \*-algebras. It is the first textbook on this topic. The first part is devoted to partial O\*-algebras, basic properties, examples, topologies on them. The climax is the generalization to this new framework of the celebrated modular theory of Tomita-Takesaki, one of the cornerstones for the applications to statistical physics. The second part focuses on abstract partial \*-algebras and their representation theory, obtaining again generalizations of familiar theorems (Radon-Nikodym, Lebesgue).…
