A broad range of problems is studied in theoretical and astrophysical relativity. The research in theoretical relativity is centered on quantum theory of dynamical systems with constraints, its ultimate goal being the clarification of the status of quantum geometrodynamics. The goal of the research in relativistic astrophysics is the application of theoretical models to astrophysical and observational issues. Three classes of projects will be investigated: 1) An improved understanding of gravitational wave generation in the late stages of gravitational collapse; 2) A Study of gravitational interactions distorting a black hole horizon; 3) Analysis of astrophysical sources of ultra high-energy cosmic rays, especially source models involving strong gravitational fields.

在理论和天体物理相对论中研究了广泛的问题。理论相对论的研究主要集中在约束动力系统的量子理论上，其最终目的是澄清量子几何动力学的地位。相对论天体物理学的研究目标是将理论模型应用于天体物理和观测问题。将研究三类项目：1)更好地理解引力崩塌后期的引力波产生；2)引力相互作用扭曲黑洞视界的研究；3)分析超高能宇宙射线的天体物理源，特别是涉及强引力场的源模型。
