鞍形连接图的大规模几何

Large-scale geometry of the saddle connection graph

Valentina Disarlo, Huiping Pan, Anja Randecker, Robert Tang

摘要:

证明了半平移曲面上的鞍形连接图是4-双曲的,并且与正则可数无限价树一致拟等距。因此,鞍形连接图不是拟等距刚性的。我们还将其Gromov边界表示为没有鞍形连接的直叶理的集合。在我们的论点中,我们给出了一个概括的独角兽路径的弧图,这可能是独立的利益。

英文摘要:

We prove that the saddle connection graph associated to any half-translation surface is 4-hyperbolic and uniformly quasi-isometric to the regular countably infinite-valent tree. Consequently, the saddle connection graph is not quasi-isometrically rigid. We also characterise its Gromov boundary as the set of straight foliations with no saddle connections. In our arguments, we give a generalisation of the unicorn paths in the arc graph which may be of independent interest.
