摘要

我们研究了大爆炸和黑洞奇点对大质量共形引力的量子效应。我们通过分析理论在这些奇点处的壳上有效作用的行为来做到这一点。结果是，这样的奇点在大质量共形重力中是无害的，因为理论的壳上有效作用在奇点处不会发散。

Singularities in massive conformal gravity

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 massive conformal gravity because the on-shell effective action of the theory does not diverge at them.
