二次微分的模空间的层端点

Ends of strata of the moduli space of quadratic differentials

Corentin Boissy

摘要:

关于二次微分的模空间的层的拓扑结构,已知的结果很少。本文证明了这类层的连通分支只有一个拓扑端点。边界邻域中的典型平坦表面自然地被平行短鞍形连接的集合分裂,但是与该分裂相关联的离散数据可能相当难以描述。为了绕过这些困难,我们使用Veech拉链矩形构造和相应的(扩展的)Rauzy类。

英文摘要:

Very few results are known about the topology of the strata of the moduli space of quadratic differentials. In this paper, we prove that any connected component of such strata has only one topological end. A typical flat surface in a neighborhood of the boundary is naturally split by a collection of parallel short saddle connections, but the discrete data associated to this splitting can be quite difficult to describe. In order to bypass these difficulties, we use the Veech zippered rectangles construction and the corresponding (extended) Rauzy classes.
