Abstract

Abstract We give a metric characterization of the scalar curvature of a smooth Riemannian manifold, analyzing the maximal distance between (n + 1) points in infinitesimally small neighborhoods of a point. Since this characterization is purely in terms of the distance function, it could be used to approach the problem of defining the scalar curvature on a non-smooth metric space. In the second part we will discuss this issue, focusing in particular on Alexandrov spaces and surfaces with bounded integral curvature.

通过局部范围的标量曲率
摘要给出了光滑黎曼流形标量曲率的度量表征,分析了点的无限小邻域中(n + 1)个点之间的最大距离。由于这种表征纯粹是用距离函数表示的,它可以用来解决在非光滑度量空间上定义标量曲率的问题。在第二部分中,我们将讨论这个问题,特别关注具有有界积分曲率的Alexandrov空间和曲面。
