Abstract
Let Λ be an associative ring. For every natural number n there is a canonical homomorphismψ n: K2,n(Λ)→K2(Λ), where K2 is the Milnor functor and K2,n(Λ) the associated unstable K-group. Dennis and Vasershtein have proved that if n is larger than the stable rank of Λ,ψ n is an epimorphism. It is proved in the article that if n − 1 is greater than the stable rank of Λ, the homomorphismψ n is an isomorphism.
