初始数据是任何数值模拟的起点。在数值相对论的情况下，爱因斯坦方程限制了我们对这些初始数据的选择。我们将研究爱因斯坦方程3 + 1分解中用于指定柯西初始数据的几种形式。然后，我们将探索如何使用这些形式化来构建包含黑洞和中子星的时空的初始数据。在讨论的主题中，重点放在那些对获得紧致双星合并的天体物理真实初始数据很重要的问题上。
Initial data are the starting point for any numerical simulation. In the case of numerical relativity, Einstein’s equations constrain our choices of these initial data. We will examine several of the formalisms used for specifying Cauchy initial data in the 3 + 1 decomposition of Einstein’s equations. We will then explore how these formalisms have been used in constructing initial data for spacetimes containing black holes and neutron stars. In the topics discussed, emphasis is placed on those issues that are important for obtaining astrophysically realistic initial data for compact binary coalescence.
