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…
Quantum gravity from the point of view of locally covariant quantum field theory
Romeo Brunetti, Klaus Fredenhagen, Katarzyna Rejzner
We construct perturbative quantum gravity in a generally covariant way. In particular our construction is background independent. It is based on the locally covariant approach to q…
Remarks on local symmetry invariance in perturbative algebraic quantum field theory
Katarzyna Rejzner
We investigate various aspects of invariance under local symmetries in the framework of perturbative algebraic quantum field theory (pAQFT). Our main result is the proof that the q…
