Using Bak's localization-completion method in [A. Bak, Nonabelian K-theory: The nilpotent class of K, and general stability, K-Theory 4 (4) (1991) 363-397], it was shown in [R. Hazrat, Dimension theory and nonstable K-1 of quadratic modules, K-Theory 514 (2002) 1-35 and R. Hazrat, N. Vavilov, K-1 of Chevalley groups are nilpotent, J. of Pure and Appl. Algebra 179 (2003) 99-116] that G/E is nilpotent by abelian, when R has finite Bass-Serre dimension. In this note, we combine localization-completion with a version of Stein's relativization [M.R. Stein, Relativizing functors on rings and algebraic K-theory, J. Algebra 19 (1) (1971) 140-152], which is applicable to our situation [A. Bak, N. Vavilov, Structure of hyperbolic unitary groups I, Elementary subgroups. Algebra Colloq. 7 (2) (2000) 159-196], and carry over the results in the latter of the two references cited above to the relative case. In other words, we prove that not only absolute K, functors, but also the relative K, functors, are nilpotent by abelian. (C) 2008 Elsevier B.V.
