The cauchy horizon
網頁在物理学中，柯西视界（英語： Cauchy horizon ）是柯西问题（偏微分方程理论的特定边值问题）有效域的轻似边界。视界的一侧包含封闭的类空测地线，另一侧包含封闭的类时测地线。这个概念以奥古斯丁·路易·柯西命名。 在平均弱能量条件（AWEC）下，柯西视界本质上是 … 網頁2024年11月10日 · (3), (9), and (10)] vanishes near the cosmological horizon. Thus, in our non-asymptotically flat black-hole spacetime, the frequency-dependent radial potential (19) of the composed black-hole-charged-field system is characterized in the large-mass regime (18) by only one extremum (maximum) point.
