摘要/Abstract

摘要： Let $(M, F)$ be an $n$-dimensional Randers space with scalar flag curvature. In this paper, we will introduce the definition of a weak Einstein manifold. We can prove that if $(M, F)$ is a weak Einstein manifold, then the flag curvature is constant.

关键词: Randers spaces, flag curvature, sectional curvature, weak Einstein manifold
