从Chern-Tenenblat到Jackiw-Teitelboim,途经sine-Gordon

From Chern-Tenenblat to Jackiw-Teitelboim via sine-Gordon

Jeff Murugan

摘要:

二维常曲率曲面的研究构成了几何学的一个美丽分支,它与可积系统的数学物理有着充分的联系。一个鲜为人知但同样令人着迷的事实是它与二维引力的联系;特别是Jackiw-Teitelboim(JT)引力,其中这种联系通过坐标选择表现出来,粗略地说,将引力场方程重新转换为sine-Gordon方程。在这种语言中,许多著名的结果,如JT-引力黑洞及其性质,被理解为sine-Gordon孤子及其性质。在这篇简短的笔记中,我们在JT引力以及更一般的低维量子引力最近一些令人兴奋的发展的背景下重新审视了这些想法,并推测其中一些新想法可能会被类似地理解。

英文摘要:

The study of 2-dimensional surfaces of constant curvature constitutes a beautiful branch of geometry with well-documented ties to the mathematical physics of integrable systems. A lesser known, but equally fascinating, fact is its connection to 2-dimensional gravity; specifically Jackiw-Teitelboim (JT) gravity, where the connection manifests through a coordinate choice that roughly speaking re-casts the gravitational field equations as the sine-Gordon equation. In this language many well-known results, such as the JT-gravity black hole and its properties, were understood in terms of sine-Gordon solitons and their properties. In this brief note, we revisit these ideas in the context of some of the recent exciting developments in JT-gravity and, more generally, low-dimensional quantum gravity and speculate on how some of these new ideas may be similarly understood.
