A Transfer Map in K -Theory

I am grateful to Keith Dennis for pointing out that the proof of Proposition 1 is fallacious. A correct argument is as follows. Let θ be the maximal order of the maximal unramified subfield ofD. Then both θ and D have residue class field d, and the following triangle of functors is commutative up to a natural equivalence: Therefore, there is a commuting triangle of homomorphisms The Proposition follows since the diagonal map is surjective by Gersten's result.
