Locally covariant quantum field theory
Klaus Fredenhagen
The principle of local covariance which was recently introduced admits a generally covariant formulation of quantum field theory. It allows a discussion of structural properties of…

Perturbative Algebraic Field Theory, and Deformation Quantization
Michael Duetsch, Klaus Fredenhagen
A perturbative formulation of algebraic field theory is presented, both for the classical and for the quantum case, and it is shown that the relation between them may be understood…
