Abstract:

A complete classification of stable homotopy types of complex and quaternionic stunted projective spaces, denoted by ${\mathbf {C}}P_n^k$ and ${\mathbf {Q}}P_n^k$ respectively, is obtained. The necessary conditions for such equivalences are found using K-theory and various characteristic classes introduced originally by J. F. Adams. As a by-product one finds the J-orders of the Hopf bundles over ${\mathbf {C}}{P^n}$ and ${\mathbf {Q}}{P^n}$ respectively. The algebraic part is rather involved. Finally a homotopy theoretical argument yields the constructions of such homotopy equivalences as are allowed by the fulfillment of the necessary conditions.
