论文摘要
本文的目的是通过考虑曲率张量的规范形式和不变性来研究SDS时空及其重力场。 $λ$ -Tensor的特征标识了重力场的类型。高斯曲率量从曲率不变的角度阐明。
The goal of this paper is to study SdS space-time and its gravitational field with consideration of the canonical form and invariants of the curvature tensor. The characteristic of $λ$-tensor identifies the type of gravitational field. Gaussian curvature quantities enunciated in terms of curvature invariants.
