This volume combines contributions in topology and representation theory that reflect the increasingly vigorous interactions between these areas. Topics such as group theory, homotopy theory, cohomology of groups, and modular representations are covered. All papers have been carefully refereed and offer lasting value. It's features include: state of the art contributions from this active, interdisciplinary branch of mathematical research; excellent, high-level survey papers by experts in the field; a unique combination of topics in algebra and topology; and, a compilation of open problems.
