双曲3-orbifolds的全测地曲面的面积

Areas of totally geodesic surfaces of hyperbolic 3-orbifolds

Benjamin Linowitz, D. B. McReynolds, Nicholas Miller

摘要:

完备的有限体积的双曲3-orbifold M的测地长度谱是M通过Mostow-Prasad刚性的拓扑的基本不变量。出于这一动机,第二作者和里德定义了一个二维模拟的测地长度谱给出了多集等距类型的全测地,沉浸,有限面积表面的M称为几何亏格频谱。他们证明了如果$M$是算术的并且包含一个全测地曲面,那么M的几何亏格谱决定了它的可拓类。在本文中,我们定义了一个粗糙的不变量称为全测地面积集给定的面积集的表面在几何亏格的频谱。我们证明了一些结果量化的程度,在何种程度上,不可压缩的算术双曲3-orbifolds可以有任意大的重叠,在他们的全测地面积集。

英文摘要:

The geodesic length spectrum of a complete, finite volume, hyperbolic 3-orbifold M is a fundamental invariant of the topology of M via Mostow-Prasad Rigidity. Motivated by this, the second author and Reid defined a two-dimensional analogue of the geodesic length spectrum given by the multiset of isometry types of totally geodesic, immersed, finite-area surfaces of M called the geometric genus spectrum. They showed that if $M$ is arithmetic and contains a totally geodesic surface, then the geometric genus spectrum of M determines its commensurability class. In this paper we define a coarser invariant called the totally geodesic area set given by the set of areas of surfaces in the geometric genus spectrum. We prove a number of results quantifying the extent to which non-commensurable arithmetic hyperbolic 3-orbifolds can have arbitrarily large overlaps in their totally geodesic area sets.
