论文摘要
我们举例说明了一个时空的示例,其连续度量是全球双曲线,并表现出因果气泡。此外,该度量将正交分成及时的零件。我们在能源条件的背景下讨论了我们的示例,以及最近引入的合成时间曲率差异(TCD)条件。特别是我们观察到TCD条件本身并不能防止因果气泡。
We give an example of a spacetime with a continuous metric which is globally hyperbolic and exhibits causal bubbling. The metric moreover splits orthogonally into a timelike and a spacelike part. We discuss our example in the context of energy conditions and the recently introduced synthetic timelike curvature-dimension (TCD) condition. In particular we observe that the TCD-condition does not, by itself, prevent causal bubbling.
