Abstract
Dedicated to the memory of V.K.A.M. Gugenheim For a simplicial group K, the realization of the W-construction WK + WK of K is shown to be naturally homeomorphic to the universal bundle E]K]--t BIK of its geometric realization]Kl. The argument involves certain recursive descriptions of the W-construction and classifying bundle and relies on the facts that the realization functor carries an action of a simplicial group to a geometric action of its realization and preserves reduced cones and colimits. @ 1998 Elsevier Science B.V.
