摘要

给定一个作用在Gromov双曲空间上的群，Bestvina和Fujiwara引入了WPD性质——弱固有不连续性——来研究该群的第二个有界上同调。我们使用Bestvina、Bromberg和Fujiwara引入的“真正的”弱性质不连续性质WWPD，对第二有界上同调进行了更一般的研究。

Second bounded cohomology and WWPD

Given a group acting on a Gromov hyperbolic space, Bestvina and Fujiwara introduced the WPD property --- weak proper discontinuity --- for studying the 2nd bounded cohomology of the group. We carry out a more general study of second bounded cohomology using a 'really' weak property discontinuity property known as WWPD that was introduced by Bestvina, Bromberg, and Fujiwara.
