Singularities in massive conformal gravity

Abstract

We study the quantum effects of big bang and black hole singularities on massive conformal gravity. We do this by analyzing the behavior of the on-shell effective action of the theory at these singularities. The result is that such singularities are harmless in MCG because the on-shell effective action of the theory does not diverge at them.
