我们描述了一个自然的关系,所有的三阶常微分方程与消失的Wunschmann不变量,与所有的共形洛伦兹度量的3流形和Cartan的正常O(3,2)共形连接。讨论了四维流形上二阶偏微分方程对的推广及其与Cartan正规O(4,2)共形联络的关系。
We describe a natural relationship between all 3rdorder ODEs with a vanishing Wunschmann invariant, with all conformal Lorentzian metrics on 3-manifolds and Cartan's normal O(3,2) conformal connections. The generalization to pairs of second order PDEs and their relationship to Cartan's normal O(4,2) conformal connections on four dimensional manifolds is discussed.
