Locally covariant approach to effective quantum gravity
Romeo Brunetti, Klaus Fredenhagen, Kasia Rejzner
Despite the fact that quantum gravity is non-renormalisable, a consistent and mathematically rigorous construction of a perturbation series is possible. This is based on the use of…
Non-trivial bundles and Algebraic Classical Field Theory
Romeo Brunetti, Andrea Moro
Inspired by the recent algebraic approach to classical field theory, we propose a more general setting based on the manifold of smooth sections of a non-trivial fiber bundle. Centr…
Unitary, anomalous Master Ward Identity and its connections to the Wess-Zumino condition, BV formalism and -algebras
Romeo Brunetti, Michael Dütsch, Klaus Fredenhagen +1
The C*-algebraic construction of QFT by Buchholz and one of us relies on the causal structure of spacetime and a classical Lagrangian. In one of our previous papers we have introdu…
