Abstract
SynopsisThe special unitary groupSU(n)has the stable homotopy type of a wedge ofn− 1 finite complexes. The ‘first’ of these complexes is ΣℂPn–1, which is well known to be indecomposable at the prime 2 whethernis finite or infinite. We show that the ‘second’ finite complex is again indecomposable at the prime 2 whennis finite, but splits into a wedge of two pieces whennis infinite.
