  Suslin proved that for an extension K/k of algebraically closed fields the
induced maps K_m(k)[n] --> K_m(K)[n] and K_m(k)/n ---> K_m(K)/n for the higher
K-groups are isomorphisms, where A[n] is the subgroup of n-torsion in an
abelien group, and A/n = A/nA, by definition. In this paper we generalize this
to other functors and other field extensions.
