Algebraic Classical and Quantum Field Theory on Causal Sets
Edmund Dable-Heath, Christopher J. Fewster, Kasia Rejzner +1
The framework of perturbative algebraic quantum field theory (pAQFT) is used to construct QFT models on causal sets. We discuss various discretised wave operators, including a new…

Locality and causality in perturbative AQFT
Kasia Rejzner
In this paper we discuss how seemingly different notions of locality and causality in quantum field theory can be unified using a non-abelian generalization of the Hammerstein prop…

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…
