Algebraic Quantum Field Theory: An Introduction
by Christopher J. Fewster, Kasia Rejzner
Publisher: arXiv.org 2019
Number of pages: 47
Description:
We give a pedagogical introduction to algebraic quantum field theory (AQFT), with the aim of explaining its key structures and features. Topics covered include: algebraic formulations of quantum theory and the GNS representation theorem, the appearance of unitarily inequivalent representations in QFT (exemplified by the van Hove model), the main assumptions of AQFT and simple models thereof, the spectrum condition, etc.
