This volume combines contributions in topology and representation theory that reflect the increasingly vigorous interactions between these areas. Topics such as

The cohomology of groups has, since its beginnings in the 1920s and 1930s, been the stage for significant interaction between algebra and topology and has led t

The theory of bounded cohomology, introduced by Gromov in the late 1980s, has had powerful applications in geometric group theory and the geometry and topology

Robert J. Zimmer is best known in mathematics for the highly influential conjectures and program that bear his name. Group Actions in Ergodic Theory, Geometry,

This book presents articles at the interface of two active areas of research: classical topology and the relatively new field of geometric group theory. It incl
