摘 要:
In this talk, we introduce the notion of the minimal norm tensor of a tensor and present the minimal normal tensors of some of well-known tensors on a Riemannian manifold. As an application, we investigate the relationships between the structure of a Riemannian manifold and the vanishing of the minimal norm tensor of some classical tensor on it.
