Heat kernel coefficients for massive gravity
Renata Ferrero, Markus B. Fröb, William C. C. Lima
We compute the heat kernel coefficients that are needed for the regularization and renormalization of massive gravity. Starting from the Stueckelberg action for massive gravity, we…
Universal definition of the non-conformal trace anomaly
Renata Ferrero, Sebastián A. Franchino-Viñas, Markus B. Fröb +1
We show that there exists a generalized, universal notion of the trace anomaly for theories which are not conformally invariant at the classical level. The definition is suitable f…
Synchronous coordinates and gauge-invariant observables in cosmological spacetimes
Markus B. Fröb, William C. C. Lima
We consider the relational approach to construct gauge-invariant observables in cosmological perturbation theory using synchronous coordinates. We construct dynamical synchronous c…
