Hermitian K-theory, Dedekind ζ-functions, and quadratic forms over rings of integers in number fields

Jonas Irgens Kylling, Oliver Röndigs, Paul Arne Østvær

We employ the slice spectral sequence, the motivic Steenrod algebra, and Voevodsky's solutions of the Milnor and Bloch-Kato conjectures to calculate the hermitian K-groups of rin…

Motivic stable homotopy groups

Daniel C. Isaksen, Paul Arne Østvær

We survey computations of stable motivic homotopy groups over various fields. The main tools are the motivic Adams spectral sequence, the motivic Adams-Novikov spectral sequence, a…

A1 contractibility of affine modifications

Adrien Dubouloz, Sabrina Pauli, Paul Arne Østvær

We introduce Koras-Russell fiber bundles over algebraically closed fields of characteristic zero. After a single suspension, this exhibits an infinite family of smooth affine A1-co…
