渐近锥流形的等周结构

Isoperimetric structure of asymptotically conical manifolds

Otis Chodosh, Michael Eichmair, Alexander Volkmann

摘要:

研究了渐近于具有非负里奇曲率的锥的黎曼流形的等周结构。具体地说,我们推广到这个设置的开创性成果G。Huisken和S.- T. Yau关于渐近平坦流形无穷远点上保体积稳定常中曲率曲面的正则叶状的存在性的结果以及第二作者与S. Brendle和J. Metzger关于渐近平坦流形的等周结构。我们还包括一个观察等周锥角等流形。这个结果是正质量定理在这种情况下的自然类比。

英文摘要:

We study the isoperimetric structure of Riemannian manifolds that are asymptotic to cones with non-negative Ricci curvature. Specifically, we generalize to this setting the seminal results of G. Huisken and S.-T. Yau on the existence of a canonical foliation by volume preserving stable constant mean curvature surfaces at infinity of asymptotically flat manifolds as well as the results of the second-named author with S. Brendle and J. Metzger on the isoperimetric structure of asymptotically flat manifolds. We also include an observation on the isoperimetric cone angle of such manifolds. This result is a natural analogue of the positive mass theorem in this setting.
