摘要

我们研究了在洛伦兹引力路径积分中通过破坏性干扰抑制具有曲率奇点的时空几何的要求，以此作为对引力微观作用的约束。基于静态球对称时空的简单例子，我们证明了路径积分中的完全奇点抑制要求引力作用在曲率上是无穷阶的。

Suppression of spacetime singularities in quantum gravity

We investigate the requirement of suppressing spacetime geometries with a curvature singularity via destructive interference in the Lorentzian gravitational path integral as a constraint on the microscopic action for gravity. Based on simple examples of static spherically symmetric spacetimes, we demonstrate that complete singularity suppression in the path integral stipulates that the action for gravity be of infinite order in the curvature.
