在本文中，我们解决了 [A.M. Alekseenko，D.N.阿诺德，爱因斯坦方程的新一阶公式，物理学。 Rev. D (3) 68 (6) (2003) 064013, 6 页]。我们规定了简单的边界条件，使问题适定并保留约束。
In this paper, we address the problem of artificial boundary conditions for the symmetric linearized hyperbolic formulation of Einstein's equations introduced in [A.M. Alekseenko, D.N. Arnold, New first-order formulation for the Einstein equations, Phys. Rev. D (3) 68 (6) (2003) 064013, 6 pp.]. We prescribe simple boundary conditions that make the problem well-posed and preserve the constraints.
