摘要

我们给出了具有边界的完全有限面积双曲面上边界分量之间有界长度的（多）弧数的渐近增长。具体地说，如果$S$具有亏格$g$、$n$边界分量和$p$删截，则每个长度至多为$L$的纯映射类群轨道中的正交几何弧的数量渐近于常数的$L^{6g-6+2（n+p）}$倍。我们证明了尖端之间的弧的类似结果，其中我们将这种弧的长度定义为通过从表面去除某些尖端区域而获得的子弧的长度。

Counting arcs on hyperbolic surfaces

We give the asymptotic growth of the number of (multi-)arcs of bounded length between boundary components on complete finite-area hyperbolic surfaces with boundary. Specifically, if $S$ has genus $g$, $n$ boundary components and $p$ punctures, then the number of orthogeodesic arcs in each pure mapping class group orbit of length at most $L$ is asymptotic to $L^{6g-6+2(n+p)}$ times a constant. We prove an analogous result for arcs between cusps, where we define the length of such an arc to be the length of the sub-arc obtained by removing certain cuspidal regions from the surface.

期刊介绍： Groups, Geometry, and Dynamics is devoted to publication of research articles that focus on groups or group actions as well as articles in other areas of mathematics in which groups or group actions are used as a main tool. The journal covers all topics of modern group theory with preference given to geometric, asymptotic and combinatorial group theory, dynamics of group actions, probabilistic and analytical methods, interaction with ergodic theory and operator algebras, and other related fields. Topics covered include: geometric group theory; asymptotic group theory; combinatorial group theory; probabilities on groups; computational aspects and complexity; harmonic and functional analysis on groups, free probability; ergodic theory of group actions; cohomology of groups and exotic cohomologies; groups and low-dimensional topology; group actions on trees, buildings, rooted trees.
