非共形物质紧致黎曼曲面上的二维量子引力

2D quantum gravity on compact Riemann surfaces with non-conformal matter

Adel Bilal, Laetitia Leduc

摘要:

本文研究了在紧致黎曼曲面上二维非共形大质量物质与引力耦合所引起的引力作用。对于任何质量值,我们用有限的、定义明确的量来表示这种引力作用。一个小质量的展开给出了无质量极限下的刘维尔作用量,一阶的马渊作用量和奥宾-丘作用量,以及一个用纯几何量表示的高阶作用量的无穷级数。

英文摘要:

We study the gravitational action induced by coupling two-dimensional non-conformal, massive matter to gravity on a compact Riemann surface. We express this gravitational action in terms of finite and well-defined quantities for any value of the mass. A small-mass expansion gives back the Liouville action in the massless limit, the Mabuchi and Aubin-Yau actions to first order, as well as an infinite series of higher-order contributions written in terms of purely geometric quantities.
