For almost two decades this has been the classical textbook on applications of operator algebra theory to quantum statistical physics. It describes the general structure of equilibrium states, the KMS-condition and stability, quantum spin systems and continuous systems.

algebras (originally called rings of operators by von Neumann himself). Commutative Banach algebras (Israel Gelfand),2 giving rise to C-algebras. So, roughly speaking, the theory of operator algebras is the same as the theory of von Neumann algebras and C-algebras.3 Let us elaborate on each of these in turn. 1.1 John von Neumann and quantum.

v. t. e. In functional analysis, a branch of mathematics, an operator algebra is an algebra of continuous linear operators on a topological vector space, with the multiplication given by the composition of mappings . The results obtained in the study of operator algebras are often phrased in algebraic terms, while the techniques used are often.

This book is addressed to graduate students and researchers working in a broad spectrum of areas in mathematics and mathematical physics. Functional analysis, operator algebras, operator theory, differential geometry, cyclic cohomology, K K -theory, and index theory are applied to questions in the quantum theory of fields and statistical.

The theory of operator algebras was initiated by von Neumann and Murray as a tool for studying group representations and as a framework for quantum mechanics, and has since kept in touch with its roots in physics as a framework for quantum statistical mechanics and the formalism of algebraic quantum field theory.

In physics, an operator is a function over a space of physical states onto another space of physical states. The simplest example of the utility of operators is the study of symmetry (which makes the concept of a group useful in this context). Because of this, they are useful tools in classical mechanics.

8. I think that recently I've started to lean in my interest more towards operator algebras and away from differential geometry, the latter having many applications to physics. But while taking physics courses, it was also brought to my attention that operator theory is a very integral part of quantum mechanics.

In the last 15-20 years mathematical physicists have realized the importance of operator algebras and their states and automorphisms for problems of field theory and statistical mechanics. But the theory of 20 years aga was largely developed for the analysis of group representations and it was inadequate for many physical applications.
