标题： Waveform propagation in black hole spacetimes: evaluating the quality of numerical solutions

摘要： 我们使用一个数值代码计算线性引力波在施瓦茨希尔德黑洞上的传播和散射，该代码求解了将齐里方程推广到三维笛卡尔坐标系的方程。由于该问题的解已被很好地理解，因此它是一个非常理想的测试平台，用于评估我们在存在黑洞事件视界的时空中执行引力波三维计算的能力。 显示英文摘要

摘要： We compute the propagation and scattering of linear gravitational waves off a Schwarzschild black hole using a numerical code which solves a generalization of the Zerilli equation to a three dimensional cartesian coordinate system. Since the solution to this problem is well understood it represents a very good testbed for evaluating our ability to perform three dimensional computations of gravitational waves in spacetimes in which a black hole event horizon is present.
