摘要
Allen (in: Volume above distance below, 2020)证明了在黎曼度量序列的直径有界的封闭流形上,如果体积收敛于极限流形的体积,黎曼度量序列\(C^0\)从下面收敛,则可以得出保体积的Sormani-Wenger内禀平面收敛。Allen等人将结果扩展到有边界的流形(见:体积收敛且距离有界的流形的固有平面稳定性,2021),通过颈部加倍过程产生封闭流形,并将有边界的情况简化为无边界的情况。用颈部加倍法的结果是在边界上要求比必要条件更强的条件。利用Allen等人对带有边界的流形上的Sormani-Wenger内禀平坦距离的估计(见:体积收敛且距离有界的带有边界的流形的内禀平坦稳定性,见下图,2021),我们表明,为了得出带有边界的流形保持体积的内禀平坦收敛的结论,只需要边界面积上的一个界。我们还提供了一个例子,表明在没有面积上的界限的情况下不应该期望收敛。
It was shown by Allen (in: Volume above distance below, 2020) that on a closed manifold where the diameter of a sequence of Riemannian metrics is bounded, if the volume converges to the volume of a limit manifold, and the sequence of Riemannian metrics are \(C^0\) converging from below then one can conclude volume preserving Sormani-Wenger Intrinsic Flat convergence. The result was extended to manifolds with boundary by Allen et al. (in: Intrinsic flat stability of manifolds with boundary where volume converges and distance is bounded below, 2021) by a doubling with necks procedure which produced a closed manifold and reduced the case with boundary to the case without boundary. The consequence of the doubling with necks procedure was requiring a stronger condition than necessary on the boundary. Using the estimates for the Sormani-Wenger Intrinsic Flat distance on manifolds with boundary developed by Allen et al. (in: Intrinsic flat stability of manifolds with boundary where volume converges and distance is bounded below, 2021), we show that only a bound on the area of the boundary is needed in order to conclude volume preserving intrinsic flat convergence for manifolds with boundary. We also provide an example which shows that one should not expect convergence without a bound on area.
