Abstract:In this talk, we show that any asymptotically flat manifold with controlled holonomy admits a refined torus fibration over an ALE manifold. In addition, we prove that any complete asymptotically flat Ricci-flat metric on $/mathbb R^4$ must be isometric to the Euclidean or the Taub-NUT metric, provided that the tangent cone at infinity is not $/mathbb R /times /mathbb R_+$. This is joint work with Xiuxiong Chen.
