Abstract:In our previous paper (Topology 38 (1999), 497–516), we discussed the hyperbolization of the configuration space of n (ge 5) marked points with weights in the projective line up to projective transformations. A variation of the weights induces a deformation. It was shown that this correspondence of the set of the weights to the Teichmüller space when n = 5 and to the Dehn filling space when n = 6 is locally one-to-one near the equal weight. In this paper, we establish its global injectivity.
Keywords:hyperbolic cone-manifold  configuration space
