在这篇文章,概括了 Birkhoff 方程被把增补术语加到 Birkhoff 方程提出。Birkhoff 方程的保角的不变性能被用来学习概括 Birkhoff 方程,并且二个例子被举说明结果的申请。
In this article, generalized Birkhoff equations are put forward by adding supplementary terms to the Birkhoff equations. A conformal invariance of the Birkhoff equations can be used to study the generalized Birkhoff Equations, and two examples are presented to illustrate the application of the results.
