论文摘要
我们找到了不均匀宇宙学数值相对性模拟的初始数据。这涉及处理一般相对性约束方程的特殊情况。我们设计了分析和数值方法来治疗这种特殊情况。我们将分析方法应用于具有单个标量场的标准宇宙学情况。数值方法应用于两场ekpyrotic宇宙学。
We find initial data for numerical relativity simulations of inhomogeneous cosmologies. This involves treating an exceptional case of the general relativity constraint equations. We devise analytic and numerical methods to treat this exceptional case. We apply the analytic method to the standard case of cosmology with a single scalar field. The numerical method is applied to the two-field ekpyrotic cosmology.
