I review the development of numerical evolution codes for general relativity based upon the characteristic initial value problem. Progress is traced from the early stage of 1D feasibility studies to current 3D codes that simulate binary black holes. A prime application of characteristic evolution is Cauchy-characteristic matching, which is also reviewed.

特征演化与匹配。


我回顾了基于特征初值问题的广义相对论数值演化代码的发展。进展可追溯到从一维可行性研究的早期阶段到当前模拟双黑洞的 3D 代码。特征演化的一个主要应用是柯西特征匹配，对此也进行了综述。
