摘要 对给定的共形流形及其中的超曲面,本文用Fefferman和Graham的辅助时空及其中齐次关联超曲面,引进了由齐次关联超曲面在辅助时空中的伪Riemann数量不变量诱导的原超曲面的共形数量不变量,提供了一套构建更多超曲面的共形数量不变量的计算方法,为寻找像Willmore方程一样关于超曲面的共形不变偏微分方程创造了路径. In this paper, we introduce the approach to use Fefferman and Graham's ambient spacetimes to calculate local scalar invariants for hypersurfaces in conformal manifolds. We are looking for scalar invariants for hypersurfaces that resemble the Willmore curvature for surfaces in Euclidean 3-space.
