Algebraic approach to Quantum Field Theory
Romeo Brunetti, Klaus Fredenhagen
We provide a short introduction to the main features of the algebraic approach to quantum field theories.
Perturbative renormalization and BRST
Michael Duetsch, Klaus Fredenhagen
The perturbative quantization of gauge theories is shortly reviewed with emphasis of the local operator BRST-formalism.
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…
