JT引力和渐近Weil-Petersson体积

JT gravity and the asymptotic Weil-Petersson volume

Yusuke Kimura

摘要:

Jackiw-Teitelboim(JT)引力中的路径积分是通过对具有边界的黎曼曲面的模的体积(称为“Weil-Petersson体积”)进行积分以及对沿边界的摆动进行积分而给出的。当亏格$g$变大时,Weil-Petersson体积$V_{g,n}(b_1, \ldots, b_n)$的精确计算变得困难。我们利用两个已知的偏微分方程来估计当亏格$g$较大时两边界体积$V_{g,2}(b_1, b_2)$和三边界体积$V_{g,3}(b_1, b_2, b_3)$的渐近行为.此外,我们提出了一个猜想的渐近表达式一般$V_{g,n}(b_1, \ldots, b_n)$与$n$边界时,$g$是大的。

英文摘要:

A path integral in Jackiw-Teitelboim (JT) gravity is given by integrating over the volume of the moduli of Riemann surfaces with boundaries, known as the "Weil-Petersson volume," together with integrals over wiggles along the boundaries. The exact computation of the Weil-Petersson volume $V_{g,n}(b_1, \ldots, b_n)$ is difficult when the genus $g$ becomes large. We utilize two partial differential equations known to hold on the Weil-Petersson volumes to estimate asymptotic behaviors of the volume with two boundaries $V_{g,2}(b_1, b_2)$ and the volume with three boundaries $V_{g,3}(b_1, b_2, b_3)$ when the genus $g$ is large. Furthermore, we present a conjecture on the asymptotic expression for general $V_{g,n}(b_1, \ldots, b_n)$ with $n$ boundaries when $g$ is large.
