This award supports several lines of investigation in classical and quantum general relativity with a common thread of numerical techniques. The particular focus will include the stability of the solution obtained from the numerical evolution of the Einstein equations when the constraints are violated, the study of initial conditions appropriate for numerical simulation of a binary system consisting of a neutron star and a black hole, and the implementation of a consistent discretization approach to quantum gravity. Some of these studies and the techniques developed through themwill allow accurate simulation of astrophysical sources of gravitational radiation for ground-based and space-based gravitational wave detectors now operating or under study. In addition, a complete, consistent approach to quantum gravity remains one of the most important unsolved problems in fundamental physics.

该奖项支持经典和量子广义相对论的几条研究线，它们都有一个共同的数值技术线索。特别的重点将包括从爱因斯坦方程的数值演化中得到的解在违反约束时的稳定性，研究适合于由中子星和黑洞组成的双星系统的数值模拟的初始条件，以及量子引力的一致离散化方法的实现。其中一些研究和通过这些研究开发的技术将使目前正在运行或正在研究的陆基和天基引力波探测器能够精确地模拟重力辐射的天体物理来源。此外，一个完整的、一致的量子引力方法仍然是基础物理学中最重要的未解决问题之一。
