State Spaces of Operator Algebras

This self-contained work, focusing on the theory of state spaces of §C -algebras and von Neumann algebras, explains how the oriented state §space geometrically determines the algebra. The theory of orientation §of C -algebra state spaces is presented with a new approach that does §not depend on Jordan algebras, and the theory of orientation of normal §state spaces of von Neumann algebras is presented with complete proofs §for the first time. The theory of operator algebras was initially §motivated by applications to physics, but has recently found §unexpected new applications to fields of pure mathematics as diverse §as foliations and knot theory. §Key features include: §first and only work devoted to state spaces of operator algebras-- §contains much material not available in existing books §prerequisites are standard graduate courses in real and complex §variables, measure theory, and functional analysis §complete proofs of basic results on operator algebras presented so §that no previous knowledge in the field is needed §detailed introduction develops basic tools used throughout the text §numerous chapter remarks on advanced topics of independent interest §with references to the literature, or discussion of applications to §physics §"State Spaces of Operator Algebras" is intended for specialists in §operator algebras, as well as graduate students and mathematicians §seeking an overview of the field. The introduction to C -algebras and §von Neumann algebras may also be of interest in it own right for those §wanting a quick introduction to basic concepts in those fields.
