渐近平坦流形上的整体Yamabe流

Global Yamabe flow on asymptotically flat manifolds

Li Ma

摘要:

本文研究了渐近平坦(简称AF或ALE)流形上整体Yamabe流的存在性。注意,ADM质量在3、4和5维中保持不变。给出了完备黎曼流形上初始度量拟等距于有界数量曲率的背景度量的Yamabe流的一个新的一般局部存在性.在初始数量曲率为非负且相应的泊松方程存在有界子解的条件下,讨论了ALE流形上Yamabe流的渐近行为.我们还给出了完备黎曼流形上一类非常一般的抛物型方程的最大值原理。

英文摘要:

In this paper, we study the existence of global Yamabe flow on asymptotically flat (in short, AF or ALE) manifolds. Note that the ADM mass is preserved in dimensions 3,4 and 5. We present a new general local existence of Yamabe flow on a complete Riemannian manifold with the initial metric quasi-isometric to a background metric of bounded scalar curvature. Asymptotic behaviour of the Yamabe flow on ALE manifolds is also addressed provided the initial scalar curvature is non-negative and there is a bounded subsolution to the corresponding Poisson equation. We also present a maximum principle for a very general parabolic equations on the complete Riemannian manifolds.
