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…
