Abstract

We calculate the motivic stable homotopy groups of the two-complete sphere spectrum after inverting multiplication by the Hopf map η over fields of cohomological dimension at most 2 with characteristic different from 2 (this includes the p –adic fields p and the finite fields F q of odd characteristic) and the field of rational numbers; the ring structure is also determined.
