Teichmuller空间的大尺度秩

Large scale rank of Teichmuller space

Alex Eskin, Howard Masur, Kasra Rafi

摘要:

设X与具有字度量的映射类群或与具有Teichmuller度量或Weil-Petersson度量的Teichmuller空间拟等距。我们引入一个统一的方法来研究这些空间的粗糙几何。我们证明了R^n中盒在X中的拟Lipschitz像局部地接近X中平坦的标准模型。作为一个结果,我们表明,所有这些空间,几何秩和拓扑秩是相等的。这些方法是公理化的,并适用于更大类的度量空间。

英文摘要:

Let X be quasi-isometric to either the mapping class group equipped with the word metric, or to Teichmuller space equipped with either the Teichmuller metric or the Weil-Petersson metric. We introduce a unified approach to study the coarse geometry of these spaces. We show that the quasi-Lipschitz image in X of a box in R^n is locally near a standard model of a flat in X. As a consequence, we show that, for all these spaces, the geometric rank and the topological rank are equal. The methods are axiomatic and apply to a larger class of metric spaces.
