论文摘要
我们使用正统框架方法为一阶的双曲线降低提供了与相当通用的物质模型相结合的一阶双曲线减少的一般框架。我们的分析涵盖了灰尘和完美液体的特殊情况。我们还提供了关于自我散发弹性物质的讨论。该框架是Fermi-Walker的传播，并选择了坐标，例如满足Lagrange条件。我们显示了爱因斯坦 - 摩尔 - 摩尔系统系统约束的传播。
We use an orthonormal frame approach to provide a general framework for the first order hyperbolic reduction of the Einstein equations coupled to a fairly generic class of matter models. Our analysis covers the special cases of dust and perfect fluid. We also provide a discussion of self-gravitating elastic matter. The frame is Fermi-Walker propagated and coordinates are chosen such as to satisfy the Lagrange condition. We show the propagation of the constraints of the Einstein-matter system.
