Algebraic Quantum Field Theory -- an introduction
Christopher J. Fewster, Kasia Rejzner
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 formulati…
Dimensional Regularization in Position Space, and a Forest Formula for Epstein-Glaser Renormalization
Michael Duetsch, Klaus Fredenhagen, Kai Johannes Keller +1
We reformulate dimensional regularization as a regularization method in position space and show that it can be used to give a closed expression for the renormalized time-ordered pr…
Spacelike localization of long-range fields in a model of asymptotic electrodynamics
Andrzej Herdegen, Katarzyna Rejzner
A previously proposed algebra of asymptotic fields in quantum electrodynamics is formulated as a net of algebras localized in regions which in general have unbounded spacelike exte…
