摘要

在本文中，我们建立了在接纳具有收缩元素的统计凸协整作用的群中，由限定子群构成的商的增长紧密性。这一结果是尖锐的，因为这些作用不能以纯指数增长的方式放松。此外，还讨论了均匀递归子群的应用。

Growth tightness of quotients by confined subgroups

In this paper, we establish the growth tightness of the quotient by confined subgroups in groups admitting the statistically convex-cocompact action with contracting elements. The result is sharp in the sense that the actions could not be relaxed with purely exponential growth. Applications to uniformly recurrent subgroups are discussed.
