WebThe Grothendieck-Witt ring GW (k) modulo the hyperbolic plane is isomorphic to the Witt ring of symmetric bilinear forms W (k) which further surjectively maps to Z/2. We may take motivic Eilenberg-Maclane spectra of Z/2, W (k) and GW (k). Voevodsky has computed the motivic Steenrod algebra of HZ/2 and solved the Bloch-Kato conjecture with its help.

Webequivariant topological sphere spectrum (which equals the Burnside ring by a result of Segal) and that of the motivic sphere spectrum (which equals the Grothendieck-Witt ring of quadratic forms by a result of Morel). Our compuation is a corollary to a tom Dieck style splitting result for certain equivariant motivic homotopy groups.
