爱因斯坦方程的一类规范

A class of gauges for the Einstein equations

Michael Reiterer, Eugene Trubowitz

摘要:

介绍了一类爱因斯坦真空方程的规范,以及三个对称双曲系统。第一个意味着规范的局部可实现性。第二类是场方程的动力学子集。第三个用于显示约束的传播。规范的正交框架形式主义,一阶,二次非线性方程。未知数为16个框架组件和28个连接组件。在仪表固定后,总共剩下33个。

英文摘要:

A class of gauges for the Einstein vacuum equations is introduced, along with three symmetric hyperbolic systems. The first implies the local realizability of the gauge. The second is the dynamical subset of the field equations. The third is used to show that the constraints propagate. The gauges are for an orthonormal frame formalism, with first order, quadratically nonlinear equations. The unknowns are 16 frame components and 28 connection components. After gauge-fixing, a total of 33 remain.
