Augmented Γ-spaces, the stable rank filtration, and a bu analogue of the Whitehead conjecture

Abstract

We explore connections between our previous paper [J. Reine Angew. Math. 604 (2007)], where we constructed spectra that interpolate between $bu$ and $\rm H\mathbb Z$, and earlier work of Kuhn and Priddy on the Whitehead conjecture and of Rognes on t
