Curtis's conjecture: the mod-2 stable Hurewicz image of the sphere is spanned by the Hopf- and Kervaire-invariant-one classes
Theorem 1.1: the image of is spanned over by the Hurewicz images of and of the Kervaire-invariant-one classes (degree ) whenever they exist; no existence is posited. Corollary 1.2: Eccles's conjecture holds for every sphere , : each nonzero spherical class in is the bottom class or a suspended Hopf-invariant-one image. Corollary 1.3 (with Hill-Hopkins-Ravenel): for outside , so the positive image vanishes above degree 126. Not shown: an exact dimension of the image or nonvanishing in each listed degree, odd primes, or Eccles's conjecture for with other than a sphere.
