Abstract
Let be a compact complex manifold, and a reduced normal crossing divisor on it, such that the logarithmic tangent bundle is holomorphically trivial. Let denote the maximal connected subgroup of the group of all holomorphic automorphisms of that preserve the divisor . Take a holomorphic Cartan geometry of type on , where are complex Lie groups. We prove that is isomorphic to for every if and only if the principal --bundle admits a logarithmic connection singular on such that is preserved by the connection .
