摘要
设是一个亏格为的紧致可定向曲面,并设是上的一个关系,使得指定弧图是Gromov双曲的且非平凡。我们证明,由此我们证明了大弧图的渐近维数是无穷的。更一般地,上的一个弧与曲线模型是上简单弧与曲线构成的图,其中通过置换顶点作用于其上。我们证明任何连通的、Gromov双曲的、余紧的弧与曲线模型满足,并且无穷型曲面上的一大类弧与曲线模型具有无穷渐近维数。

备注
19 pages. Asymptotic dimension bounds now apply to connected graphs whose vertices are finite collections of (possibly intersecting) simple arcs and curves. We show any such graph on a compact surface S admitting a cocompact action of PMap(S) is equivariantly quasi-isometric to a graph of markings likewise admitting a cocompact action, which suffices to generalize the techniques of the paper
