Given integers$g,n\geqslant 0$ satisfying$2-2g-n<0$ , let${\mathcal{M}}_{g,n}$ be the moduli space of connected, oriented, complete, finite area hyperbolic surfaces of genus$g$ with$n$ cusps. We study the global behavior of the Mirzakhani function$B:{\mathcal{M}}_{g,n}\rightarrow \mathbf{R}_{{\geqslant}0}$ which assigns to$X\in {\mathcal{M}}_{g,n}$ the Thurston measure of the set of measured geodesic laminations on$X$ of hyperbolic length${\leqslant}1$ . We improve bounds of Mirzakhani describing the behavior of this function near the cusp of${\mathcal{M}}_{g,n}$ and deduce that$B$ is square-integrable with respect to the Weil–Petersson volume form. We relate this knowledge of$B$ to statistics of counting problems for simple closed hyperbolic geodesics.

给定整数$g,n\geqslant 0$ 令人满意的$2-2g-n<0$ , 让${\mathcal{M}}_{g,n}$ 是属的连通的、有向的、完全的、有限面积的双曲曲面的模空间$g$ 和$n$ 风口浪尖。我们研究 Mirzakhani 函数的全局行为$B:{\mathcal{M}}_{g,n}\rightarrow \mathbf{R}_{{\geqslant}0}$ 分配给$X\in {\mathcal{M}}_{g,n}$ 测量的测地线叠片集的瑟斯顿测量值$X$ 双曲线长度${\leqslant}1$ . 我们改进了 Mirzakhani 的边界,描述了该函数在${\mathcal{M}}_{g,n}$ 并推断出$B$ 是关于 Weil-Petersson 体积形式的平方可积的。我们把这些知识联系起来$B$ 统计简单闭合双曲测地线的计数问题。
