Abstract

Let kqkq denote the very effective cover of Hermitian K-theory. We apply the kqkq-based motivic Adams spectral sequence, or kqkq-resolution, to computational motivic stable homotopy theory. Over base fields of characteristic not two, we prove that the nn-th stable homotopy group of motivic spheres is detected in the first nn lines of the kqkq-resolution, thereby reinterpreting results of Morel and R{\"o}ndigs-Spitzweck-{\O}stv{\ae}r in terms of kqkq and kqkq-cooperations. Over algebraically closed fields of characteristic 0, we compute the ring of kqkq-cooperations modulo v1v_1-torsion, establish a vanishing line of slope 1/51/5 in the E2E_2-page, and completely determine the 00- and 11- lines of the kqkq-resolution. This gives a full computation of the v1v_1-periodic motivic stable stems and recovers Andrews and Miller's calculation of the η\eta-periodic C\mathbb{C}-motivic stable stems. We also construct a motivic connective jj spectrum and identify its homotopy groups with the v1v_1-periodic motivic stable stems. Finally, we propose motivic analogs of Ravenel's Telescope and Smashing Conjectures and present evidence for both.
