In this article we study the metric property and the function theory of asymptotically locally Euclidean (ALE) Kahler manifolds. In particular, we prove the Ricci flatness under the assumption that the Ricci curvature of such manifolds is either nonnegative or nonpositive. The result provides a generalization of previous gap type theorems established by Greene and Wu, Mok, Sin and Yau, etc. It can also be thought of as a general positive mass type result. The method also proves the Liouville properties of plurisub harmonic functions on such manifolds. We also give a characterization of Ricci flatness of an ALE Kahler manifold with nonnegative Ricci curvature in terms of the structure of its cone at infinity.http://gateway.webofknowledge.com...
