### On the K-theory and topological cyclic homology of smooth
schemes over a discrete valuation ring (with Thomas Geisser)

Let V be a discrete valuation ring of mixed characteristic (0,p) and
let X be a smooth and proper scheme over V. We show that with
**Z**/p^{v}-coefficients, the cyclotomic trace induces an
isomorphism of the Dwyer-Friedlander etale K-theory of X and the
topological cyclic homology of X.
