普通的柯西演化仅在初始数据表面的依赖域内确定偏微分方程的解。因此,在非全局双曲时空中,不存在完全确定的动力学。我们在这里表明,对于克莱因-戈登标量场在任意静态时空中传播的情况,可以给出物理上合理的、完全确定的动力学演化处方。如果宇宙审查假说应该被推翻,这种处方可以拯救确定性物理学。
Ordinary Cauchy evolution determines a solution of a partial differential equation only within the domain of dependence of the initial data surface. Hence, in a nonglobally hyperbolic space‐time, one does not have fully deterministic dynamics. We show here that for the case of a Klein–Gordon scalar field propagating in an arbitrary static space‐time, a physically sensible, fully deterministic dynamical evolution prescription can be given. If the cosmic censor hypothesis should be overthrown, a prescription of this sort could rescue deterministic physics.
