The present volume contains papers from internationally distinguished research workers that reflect recent exciting breakthroughs in this field. It will be important for all homotopy theorists as both a statement of current research and as a signpost for new directions. This should prove interesting to research workers in algebraic topology.Preface; Publications of I. M. James; 1. Homotopy fixed points in the algebraic K-theory of certain infinite discrete groups G.
