题目:The uniqueness of Poincare type extremal Kahler metric
摘要:Let D be a smooth divisor on a closed Kahler manifold X. Suppose that Aut_0(D)={Id}. We prove that the Poincare type extremal Kahler metric with a cusp singularity at D is unique up to a holomorphic transformation on X that preserves D. This generalizes Berman-Berndtsson's work on the uniqueness of extremal Kahler metrics from closed manifolds to some complete and noncompact manifolds.
