一类调和Einstein方程的保约束边界处理

Constraint-preserving boundary treatment for a harmonic formulation of the Einstein equations

Jennifer Seiler, Bela Szilagyi, Denis Pollney, Luciano Rezzolla

摘要:

我们提出了一组适定的约束保持边界条件的一阶在时间上,二阶在空间上,调和制定的爱因斯坦方程。边界条件进行了测试,使用强大的稳定性,线性和非线性波,并被发现是反射和约束保持比标准的索末菲型边界条件。

英文摘要:

We present a set of well-posed constraint-preserving boundary conditions for a first-order in time, second-order in space, harmonic formulation of the Einstein equations. The boundary conditions are tested using robust stability, linear and nonlinear waves, and are found to be both less reflective and constraint preserving than standard Sommerfeld-type boundary conditions.
