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