We study certain cross-effects of the unstable homotopy of spheres. These cross-effects were constructed by Weiss, for different purposes, in the context of “Orthogonal calculus”. We show that Mithchell’s finite spectra with Akfree cohomology (constructed in [Mt85]) arise naturally as stabilizations of Weiss’ cross-effects. Moreover, we find that after a… (More)
