Two-primary algebraic K-theory of rings of integers in number fields, by John Rognes and Chuck Weibel

We relate the algebraic K-theory of a totally real number field F to its étale cohomology. We also relate it to the zeta-function of F when F is Abelian. This establishes the two-primary part of the `Lichtenbaum conjectures.' To do this we compute the two-primary K-groups of F and of its ring of integers, using recent results of Voevodsky and the Bloch-Lichtenbaum spectral sequence, modified for finite coefficients in an appendix. A second appendix, by M. Kolster, explains the connection to the zeta-function and Iwasawa theory.
