Multiplicative Renormalization in Causal Perturbation Theory
Jonah Epstein, Arne Hofmann, David Prinz
We construct multiplicative renormalization for the Epstein--Glaser renormalization scheme in perturbative Algebraic Quantum Field Theory: To this end, we fully combine the Connes-…
Cancellation Identities and Renormalization
David Prinz
We construct a manifest gauge invariant renormalization framework by first introducing a perturbative BRST Feynman graph complex and then combining it with Connes--Kreimer renormal…
Renormalization of Gauge Theories and Gravity
David Prinz
We study the perturbative quantization of gauge theories and gravity. Our investigations start with the geometry of spacetimes and particle fields. Then we discuss the various Lagr…
Algebraic Structures in the Coupling of Gravity to Gauge Theories
David Prinz
This article is an extension of the author's second master thesis [1]. It aims to introduce to the theory of perturbatively quantized General Relativity coupled to Spinor Electrody…
