我们研究的外尔室长度紧的希钦和最大的字符品种,并确定其中的一个开放的不连续的映射类组的行动。这个结果是作为一个典型的分解的有限型表面上的测地线电流所产生的拓扑分解的表面沿着特殊测地线的结果。我们发现,每个组件要么是相关的测量层压或具有积极的收缩。对于目前的积极收缩,我们表明,在一组封闭的曲线上的交叉功能是bilipschitz等价于长度函数的双曲度量。
We study the Weyl chamber length compactification both of the Hitchin and of the maximal character varieties and determine therein an open set of discontinuity for the action of the mapping class group. This result is obtained as a consequence of a canonical decomposition of a geodesic current on a surface of finite type arising from a topological decomposition of the surface along special geodesics. We show that each component either is associated to a measured lamination or has positive systole. For a current with positive systole, we show that the intersection function on the set of closed curves is bilipschitz equivalent to the length function with respect to a hyperbolic metric.
