摘要

Athreya, Bufetov, Eskin和Mirzakhani证明了在Teichm\ {u}ller空间中与半径$R$的闭球相交的映射类群格点的个数渐近于$e^{hR}$，其中$h$是Teichm\ {u}ller空间的维数。与此相反，我们证明了与半径$R$的闭球相交的Dehn捻格点的个数大致渐近于$e^{\frac{h}{2}R}$。此外，我们证明了与半径$R$的封闭球相交的多重扭转点数至少以$R \cdot e^{\frac{h}{2}R}$的速率粗略增长。

Growth rate of dehn twist lattice points in teichmuller space

Athreya, Bufetov, Eskin and Mirzakhani have shown the number of mapping class group lattice points intersecting a closed ball of radius $R$ in Teichm\"{u}ller space is asymptotic to $e^{hR}$, where $h$ is the dimension of the Teichm\"{u}ller space. In contrast we show the number of Dehn twist lattice points intersecting a closed ball of radius $R$ is coarsely asymptotic to $e^{\frac{h}{2}R}$. Moreover, we show the number multi-twist lattice points intersecting a closed ball of radius $R$ grows coarsely at least at the rate of $R \cdot e^{\frac{h}{2}R}$.

期刊介绍： This journal is devoted to topology and analysis, broadly defined to include, for instance, differential geometry, geometric topology, geometric analysis, geometric group theory, index theory, noncommutative geometry, and aspects of probability on discrete structures, and geometry of Banach spaces. We welcome all excellent papers that have a geometric and/or analytic flavor that fosters the interactions between these fields. Papers published in this journal should break new ground or represent definitive progress on problems of current interest. On rare occasion, we will also accept survey papers.
