曲线复形的商
Quotients of the curve complex
摘要:
本文考虑了由一致拟凸子空间锥化得到的曲线复形的三种形式:对称曲线集、非极大训练轨道集和压缩体圆盘集。我们证明了映射类群对这些子的作用是强WPD的,这意味着这些作用是非初等的,并且这些子是无限直径的。
英文摘要:
We consider three kinds of quotients of the curve complex which are obtained by coning off uniformly quasi-convex subspaces: symmetric curve sets, non-maximal train track sets, and compression body disc sets. We show that the actions of the mapping class group on those quotients are strongly WPD, which implies that the actions are non-elementary and those quotients are of infinite diameter.
