摘要：

我们给出了一个替代的定义相对双曲的基础上的性质最近点投影的周边子群。我们还推导出一个距离公式相对双曲群，类似于一个映射类群。

英文摘要：

We give an alternative definition of relative hyperbolicity based on properties of closest-point projections on peripheral subgroups. We also derive a distance formula for relatively hyperbolic groups, similar to the one for mapping class groups.
