A C*-algebraic Approach to Interacting Quantum Field Theories
A C*-algebraic Approach to Interacting Quantum Field Theories
A novel C*-algebraic framework is presented for relativistic quantum field theories, fixed by a Lagrangean. It combines the postulates of local quantum physics, encoded in the Haag-Kastler axioms, with insights gained in the perturbative approach to quantum field theory. Key ingredients are an appropriate version of Bogolubov's relative $S$-operators and …
