Abstract
In this article we study the torsion in the second Chow group of a smooth, projective scheme over a Henselian discrete valuation ring with finite or separably closed residue field. We show that the prime to p torsion of this group injects into the prime to p torsion of the special fibre (where p is the characteristic of the residue field). Using this result, we prove the finiteness of the prime to p torsion in the second Chow group of certain varieties over p-adic fields. We also prove similar results for other K-cohomology groups.
