关于具有有界几何的黎曼流形中的簇与多重等周剖面

On clusters and the multi-isoperimetric profile in Riemannian manifolds with bounded geometry

Reinaldo Resende

AI总结:

本文在具有有界几何的完备黎曼流形中证明等周簇的存在性、紧性及有界性,引入并证明多重等周剖面的Hölder连续性,从而将经典等周问题推广到黎曼等周簇背景。

摘要:

对于具有有界几何的完备黎曼流形,我们证明了等周簇的存在性,以及在一个通过添加有限多个无穷远极限流形而得到的更大空间中簇序列的紧性定理。此外,我们证明了等周簇是有界的。我们引入并证明了多重等周剖面的Hölder连续性,该剖面此前由Emanuel Milman和Joe Neeman利用高斯加权周长概念进行过探索。利用本文给出的结果,我们给出了经典存在性定理的一个证明,例如在空间形式中等周簇的存在性。本文的结果将Stefano Nardulli、Andrea Mondino、Frank Morgan、Matteo Galli和Manuel Ritoré先前关于经典黎曼与次黎曼等周问题的工作推广到黎曼等周簇的背景下,同时也推广了Frank Morgan和Francesco Maggi在欧氏空间中关于簇理论的工作。

英文摘要:

For a complete Riemannian manifold with bounded geometry, we prove the existence of isoperimetric clusters and also the compactness theorem for sequence of clusters in a larger space obtained by adding finitely many limit manifolds at infinity. Moreover, we show that isoperimetric clusters are bounded. We introduce and prove the Holder continuity of the multi-isoperimetric profile which has been explored by Emanuel Milman and Joe Neeman with a Gaussian-weighted notion of perimeter. We yield a proof of classical existence theorem, e.g. in space forms, for isoperimetric cluster using the results presented here. The results in this work generalize previous works of Stefano Nardulli, Andrea Mondino, Frank Morgan, Matteo Galli and Manuel Ritoré from the classical Riemannian and sub-Riemannian isoperimetric problem to the context of Riemannian isoperimetric clusters and also Frank Morgan and Francesco Maggi works on the clusters theory in the Euclidean setting.
