论文摘要
里德询问映射类组的所有凸形结合亚组是否可分开。使用Manning-Mj-Sageev的构造，我们给出了不含任意有限等级的可分离凸形结合子组的示例，而事先示例似乎几乎都是循环的。
Reid asked whether all convex-cocompact subgroups of mapping class groups are separable. Using a construction of Manning-Mj-Sageev, we give examples of separable convex-cocompact subgroups that are free of arbitrary finite rank, while prior examples seem to all be virtually cyclic.
