Suppose A is a local ring essentially of finite type and smooth over a discrete valuation ring R. The author proves that the Gersten resolution \(0\to K_ 2(A)\to \coprod_{cod 0}K_ 2(k(x))\to \coprod_{cod 1}k(x)^*\to \coprod_{cod 0}{\mathbb{Z}}\to 0\quad is\) exact, where the direct sums are taken over all cycles of the indicated codimension.
