Etale descent for real number fields, by Paul Arne Østvær

In this paper we verify the strong Quillen-Lichtenbaum conjecture for integers in real number fields at the prime two. That is, we prove that the Dwyer-Friedlander map from mod two algebraic K-theory to mod two etale topological K-theory is a weak equivalence on zero-connected covers for two-integers in real number fields. The proof is given by comparing two explicit calculations.
