标题： Gravitational collapse in Quantum Einstein Gravity

摘要： 时空奇点的存在是当今物理学最大的问题之一。 根据彭罗斯的说法，每个物理奇点都应该被一个“宇宙审查者”所覆盖，以防止任何外部观察者感知到它们的存在。 然而，描述引力坍缩的经典模型通常会导致强曲率奇点，这些奇点也可能在有限的先进时间内保持“裸露”状态。 本文档研究了渐近安全引力对典型Vaidya时空引力坍缩所引起的修正。 结果表明，对于任何可能的质量函数选择，量子引力都会使内部奇点在引力上变得较弱，从而允许时空在奇点之外进行连续延拓。 显示英文摘要

摘要： The existence of spacetime singularities is one of the biggest problems of nowadays physics. According to Penrose, each physical singularity should be covered by a "cosmic censor" which prevents any external observer from perceiving their existence. However, classical models describing the gravitational collapse usually results in strong curvature singularities, which can also remain "naked" for a finite amount of advanced time. This proceedings studies the modifications induced by Asymptotically Safe Gravity on the gravitational collapse of generic Vaidya spacetimes. It will be shown that, for any possible choice of the mass function, Quantum Gravity makes the internal singularity gravitationally weak, thus allowing a continuous extension of the spacetime beyond the singularity.
