标题： Comparison of metrics obtained with analytic perturbation theory and a numerical code

摘要： 我们将通过解析微扰理论获得的度量与它们的数值对应物进行比较。 解析解是通过Cabezas等人(2007)提出的CMMR后闵可夫斯基和慢旋转近似方法计算的，用于一个包含旋转完美流体致密源的渐近平坦静态时空。 同样的时空使用AKM数值多域谱代码(Ansorg等, 2002,2003)进行研究。 然后我们研究它们在源内部、无限远处以及匹配面上的差异，或者等效地，解析微扰方案的整体特性。 显示英文摘要

摘要： We compare metrics obtained through analytic perturbation theory with their numerical counterparts. The analytic solutions are computed with the CMMR post-Minkowskian and slow rotation approximation due to Cabezas et al. (2007) for an asymptotically flat stationary spacetime containing a rotating perfect fluid compact source. The same spacetime is studied with the AKM numerical multi-domain spectral code (Ansorg et al., 2002,2003). We then study their differences inside the source, near the infinity and in the matching surface, or equivalently, the global character of the analytic perturbation scheme.
