描述In this book we give a complete geometric description of state spaces of operator algebras, Jordan as well as associative. That is, we give axiomatic characterizations of those convex sets that are state spaces of C*-algebras and von Neumann algebras, together with such characterizations for the normed Jordan algebras called JB-algebras and JBW-algebras. These non­ associative algebras generalize C*-algebras and von Neumann algebras re­ spectively, and the characterization of their state spaces is not only of interest in itself, but is also an important intermediate step towards the characterization of the state spaces of the associative algebras. This book gives a complete and updated presentation of the character­ ization theorems of [10]‘ [11] and [71]. Our previous book State spaces of operator algebras: basic theory, orientations and C*-products, referenced as [AS] in the sequel, gives an account of the necessary prerequisites on C*-algebras and von Neumann algebras, as well as a discussion of the key notion of orientations of state spaces. For the convenience of the reader, we have summarized these prerequisites in an appendix which contains all relevant definitions and resul

Structure of JBW-algebrasay–von Neumann equivalence of projections in von Neumann algebras.) We will define the notion of type I and type I.JBW-algebras, and describe the classification of type I.JBW-factors. (For the sake of brevity, most of these results will be stated without proof, with references given to [67].) Finall

Representations of JB-algebrasat there is one crucial difference compared to the situation for C*- algebras: not every JB-algebra admits such a concrete representation. The “Gelfand–Naimark” type theorem (Theorem 4.19) states that there is a certain exceptional ideal, and modulo that ideal every JB-algebra admits a concrete repr

Dynamical Correspondencesespondence of observables and generators of one-parameter groups of automorphisms in quantum mechanics. It is closely related to Connes’ concept of orientation [36, Definition 4.11] that he used as a key property in his characterization of the natural self-dual cones associated with von Neumann alge

General Compressions be strengthened to characterize the state spaces of Jordan and C.-algebras. The first part of this program is to establish a satisfactory spectral theory and functional calculus. Here the guiding idea is to replace projections.by “projective units”.P1 determined by “general compressions”.defined by

Characterization of C*-algebra State SpacesC.-algebras have an identity, but our characterization can easily be adapted for non-unital algebras). We will start with our previous charac­terization of state spaces of JB-algebras (Theorem 9.38). Then we will add two additional properties that characterize C.-state spaces among state spaces of J
