General Covariance in Algebraic Quantum Field Theory
Romeo Brunetti, Martin Porrmann, Giuseppe Ruzzi
In this review we report on how the problem of general covariance is treated within the algebraic approach to quantum field theory by use of concepts from category theory. Some new…
p-Nuclearity in a New Perspective
Christopher J. Fewster, Izumi Ojima, Martin Porrmann
In this paper we try to settle some confused points concerning the use of the notion of p-nuclearity in the mathematical and physical literature, pointing out that the nuclearity i…
Particle Weights and their Disintegration II
Martin Porrmann
The first article in this series presented a thorough discussion of particle weights and their characteristic properties. In this part a disintegration theory for particle weights…
Particle Weights and their Disintegration I
Martin Porrmann
The notion of Wigner particles is attached to irreducible unitary representations of the Poincare group, characterized by parameters m and s of mass and spin, respectively. However…
The Concept of Particle Weights in Local Quantum Field Theory
Martin Porrmann
The concept of particle weights has been introduced by Buchholz and the author in order to obtain a unified treatment of particles as well as (charged) infraparticles which do not…
