Torsion in finite H-spaces and the homotopy of the three-sphere
Let X be a 2-connected p-local finite H-space with a single cell in dimension three. We give a simple cohomological criterion which distinguishes when the inclusion i: S 3 i ? X has the property that the loop of its three-connected cover is null homotopic. In particular, such a null homotopy implies that ? m (i)=0 for m?4 . Applications are made to Harper's rank 2 finite H -space and simple, simply-connected, compact Lie groups.

Abstract
Let X be a 2-connected p-local finite H-space with a single cell in dimension three. We give a simple cohomological criterion which distinguishes when the inclusion i: S 3 i ? X has the property that the loop of its three-connected cover is null homotopic. In particular, such a null homotopy implies that ? m (i)=0 for m?4 . Applications are made to Harper's rank 2 finite H -space and simple, simply-connected, compact Lie groups.
