Partial *Algebras and Their Operator Realizationsby Jeanpierre Antoine
Synopses & ReviewsPublisher Comments: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 TomitaTakesaki, 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 (RadonNikodym, Lebesgue).
Book News Annotation:This book considers partial *algebras of unbounded operators (partial O*algebras) and their underlying algebraic structure, partial * algebras. Early chapters are devoted to partial O*algebras, basic properties, examples, and topologies, and a generalization of this new framework to the modular theory of TomitaTakesaki is presented. Later chapters focus on abstract partial *algebras and their representation theory. There is also material on partial *algebras of operators on Rigged Hilbert Spaces, and some examples of applications in mathematical physics are included. Antoine is affiliated with the Universit<'e> Catholique de Louvain, Belgium. Annotation (c)2003 Book News, Inc., Portland, OR (booknews.com)
Synopsis: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 Japanese mathematicians. This is the first textbook to go one step further by considering systematically partial *algebras of unbounded operators (partial O*algebras) and the underlying algebraic structure, namely, partial *algebras. The first part of the text begins with partial O*algebras covering basic properties and topologies with many examples and accumulates in the generalization to this new framework of the celebrated modular theory of TomitaTakesaki, one of the cornerstones for the applications to statistical physics. The text then focuses on abstract partial *algebras and their representation theory, again obtaining generalizations of familiar theorems, for example RadonNikodym and Lebesgue. Partial *algebras of operators on Rigged Hilbert Spaces are also considered. The last chapter discusses some applications in mathematical physics, for example quantum field theory and spin systems. This book will be of interest to graduate students or researchers in pure mathematics as well as mathematical physicists.
