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…
Local Structure of Sprinkled Causal Sets
Christopher J. Fewster, Eli Hawkins, Christoph Minz +1
We describe numerical and analytical investigations of causal sets sprinkled into spacetime manifolds. The first part of the paper is a numerical study of finite causal sets sprink…
Cosmological perturbation theory and quantum gravity
Romeo Brunetti, Klaus Fredenhagen, Thomas-Paul Hack +2
It is shown how cosmological perturbation theory arises from a fully quantized perturbative theory of quantum gravity. Central for the derivation is a non-perturbative concept of g…
