Curvature bounds for the spectrum of closed Einstein spaces and Simon conjecture

ShanLin Guan, Zhen Guo

Let $(M^{n}, g)$ be a closed connected Einstein space, $n = d im M,$ and $κ_{0}$ be the lower bound of the sectional curvature. In this paper, we prove Udo Simon's conjecture: on cl…

Minimal Norm Tensors Principle and its Applications

Zhen Guo, ShanLin Guan

In this paper we study the minimal norm tensors for general third covariant tensors and fourth covariant tensors, using this we can give a new explanation of Weyl tensor and Cotten…
