关于拟凸性和相对双曲结构

On Quasiconvexity and Relative Hyperbolic Structures

Eduardo Martinez-Pedroza

摘要:

设G是一个相对于子群集合A是双曲的群,它相对于子群集合B也是双曲的。假设集合A包含B。我们刻画了G的子群相对于A的拟凸性蕴涵相对于B的拟凸性的条件。我们还证明了相对于B的拟凸性蕴涵相对于A的拟凸性。一些应用进行了讨论。

英文摘要:

Let G be a group which is hyperbolic relative to a collection of subgroups A, and it is also hyperbolic relative to a collection of subgroups B. Suppose that the collection A contains B. We characterize, for subgroups of G, when quasicovexity relative to A implies quasiconvexity relative to B. We also show that quasiconvexity relative to B implies quasiconvexity relative to A. Some applications are discussed.
