UNSTABLE SPLITTINGS OF CLASSIFYING SPACES OF P-COMPACT GROUPS D.Notbohm Dwyer and Wilkerson gave a definition of a p-compact group , which is a loop space with certain properties and a good generalisation of the notion of compact lie groups in terms of classifying spaces and homotopy theory; e.g. every p-compact group has a maximal torus, a normalizer of the maximal torus and a Weyl group. The believe or hope that p-compact groups enjoy most properties of compact Lie groups establishes a program for the classification of these objects. Following the classification of connected compact Lie groups, one step in this program is to show that every simply connected p-compact group splits into a product of simply connected simple p-compact groups. The proof of this splitting theorem is based on the fact that every classifying space of a \pcg\ splits into a product if the normalizer of the maximal torus does.
