论文摘要
与$ OUT（f_n）$在外层空间的动作类似，广义的Baumslag SOLIRAR组的外部自动形态群在具有Lipschitz指标的变形空间上，以及与火车轨道代表的任何完全不可估的自闭症的动作。受Algom-Kfir先前的工作的启发，我们证明了这种自动形态的轴是强烈收缩的。
Similarly to the action of $Out(F_N)$ on Outer Space, the outer automorphism group of a Generalized Baumslag Solitar group acts on a deformation space endowed with the Lipschitz metric and the action of any fully irreducible automorphism with a train track representative is hyperbolic. Inspired by previous work by Algom-Kfir, we prove that the axis of such an automorphism is strongly contracting.
