Stable motivic homotopy theory at infinity

Adrien Dubouloz, Frédéric Déglise, Paul Arne Østvær

In this paper, we initiate a study of motivic homotopy theory at infinity. We use the six functor formalism to give an intrinsic definition of the stable motivic homotopy type at i…

The second stable homotopy groups of motivic spheres

Oliver Röndigs, Markus Spitzweck, Paul Arne Østvær

We compute the 2-line of stable homotopy groups of motivic spheres over fields of characteristic not two in terms of motivic cohomology and hermitian K-groups.
