中文摘要 AI 辅助

本文刻画了闭双曲三维流形上测地流与共形流的交集。我们借此证明了若干涉及负曲率度量的Liouville熵、极小曲面熵与面积比的精确界。利用这些思路,我们还给出了三维情形下Mostow Rigidity Theorem(莫斯托刚性定理)的一种新证明。

英文摘要

In this paper, we describe the intersection between geodesic and conformal currents on closed hyperbolic three-manifolds. We use this to prove some sharp bounds which involve the Liouville entropy of a negatively curved metric, the minimal surface entropy, and the area ratio. Using these ideas we also give a new proof of the Mostow Rigidity Theorem in the three-dimensional case.
