论文摘要
我们考虑了明确定义的时空建模黑洞蒸发中的黑洞信息问题。使用此上下文，我们回顾了问题的基本方面，并特别努力对微妙的主题进行明确的努力，例如，在各种情况下，熵的含义。然后，我们专注于单位性问题，并认为通常会违反长期，蒸发时间和页面时间“单位性”的半经典陈述，即使物理学基本上是统一的，也可能会违反。这表明没有地平线防火墙。我们讨论如何修改图片以定期（非发音）蒸发模型。我们还将我们的结论与最近的全息研究进行了比较，并认为它们是相互兼容的。
We consider the black hole information problem in an explicitly defined spacetime modelling black hole evaporation. Using this context we review basic aspects of the problem, with a particular effort to be unambiguous about subtle topics, for instance precisely what is meant by entropy in various circumstances. We then focus on questions of unitarity, and argue that commonly invoked semiclassical statements of long term, evaporation time, and Page time "unitarity" may all be violated even if physics is fundamentally unitary. This suggests that there is no horizon firewall. We discuss how the picture is modified for regular (nonsingular) evaporation models. We also compare our conclusions to recent holographic studies, and argue that they are mutually compatible.
