曲面的组合里奇流的性质

On the properties of the combinatorial Ricci flow for surfaces

Emil Saucan

摘要:

我们研究曲面的组合里奇流的性质,包括向前和向后的存在性、唯一性和奇点的形成。我们表明,存在的顺利里奇流的积极结果也适用于组合的,而且,同样的结果适用于一个更一般的,度量曲率的概念。利用度量曲率的方法,我们证明了分段常曲率多面体流形的里奇流的存在性。本文还研究了该流程在$\mathbb{R}^3$中的可实现性问题。

英文摘要:

We investigate the properties of the combinatorial Ricci flow for surfaces, both forward and backward -- existence, uniqueness and singularities formation. We show that the positive results that exist for the smooth Ricci flow also hold for the combinatorial one and that, moreover, the same results hold for a more general, metric notion of curvature. Furthermore, using the metric curvature approach, we show the existence of the Ricci flow for polyhedral manifolds of piecewise constant curvature. We also study the problem of the realizability of the said flow in $\mathbb{R}^3$.
