  • Differential Geometry
  • Functional Analysis
  • Operator Theory
  • Quantum Information Theory

Commutation relations and traces

Monday the 8th of March, 2021, 12:30, Online Seminar:

Canonical commutation relations are one of the fundamental tools to describe kinematics of quantum systems. These relations can be encoded to the C*-algebra framework in different ways. The Weyl algebra (due to Weyl and von Neumann) is generated by exponentials of the fields satisfying the relations or, more recently, the resolvent algebra (due to Buchholz and Grundling) which is generated by the resolvents of the fields. We will analyze these algebras in relation to the existence of certain kinds of traces and focusing on 'amenable' approximations by means of finite structures.
