AI 中文摘要
我们计数亏格2平铺曲面的零全纯$\u2119$-覆盖上,在$\u2119$-作用意义下的极大圆柱,得到二次渐近式。我们还证明了该渐近式的首项,即Siegel-Veech常数,可以通过中间有限覆盖的大亏格近似来恢复。我们的工作适用于P. Hubert和G. Weitze-Schmithüsen引入的无限阶梯。对于该族的许多成员,我们显式计算了相关的Siegel-Veech常数。特别地,我们展示了零全纯$\u2119$-覆盖中第一个无限族例子,其中圆柱数量以次二次方式增长。
英文摘要
We count maximal cylinders on zero holonomy $\mathbb{Z}$-covers of genus $2$ square-tiled surfaces, up to $\mathbb{Z}$-action, obtaining quadratic asymptotics. We also show that the leading term of the asymptotic, called the Siegel-Veech constant, can be recovered via a large-genus approximation by intermediate finite covers. Our work applies to the infinite staircases introduced by P. Hubert and G. Weitze-Schmithüsen. For many members of this family, we explicitly compute the associated Siegel-Veech constants. In particular, we exhibit the first infinite family of examples of zero holonomy $\mathbb{Z}$-cover in which the number of cylinders grows sub-quadratically.
