Query: Bounded cohomology of amenable covers via classifying spaces   Gromov and Ivanov established an analogue of Leray's theorem on cohomology of
contractible covers for bounded cohomology of amenable covers. We present an
alternative proof of this fact, using classifying spaces of families of
subgroups.
