Two Kleinian groups Gamma(1) and Gamma(2) are said to be topologically
conjugate when there is a homeomorphism f : S-2 --> S-2 such that f G
amma(1)f(-1) = Gamma(2). It is conjectured that if two Kleinian groups
Gamma(1) and Gamma(2) are topologically conjugate, one is a quasi-con
formal deformation of the other. In this paper generalizing Minsky's r
esult, we shall prove that this conjecture is true when Gamma(1) is fi
nitely generated and freely indecomposable, and the injectivity radii
of all points of H-3/Gamma(1) and H-3/Gamma(2) are bounded below by a
positive constant.
