摘要: 通过求解2+1维de—Sitter时空中零测地线方程得到光线的轨迹方程,对轨迹方程进行分析发现其不存在封闭的轨迹解.

关键词: de—Sitter时空, 测地线, 光线轨迹

Abstract: Solving the geodesic equation in (2+1) dimensional de-Sitter space-time, we obtain the trace equation of ray. Analysing the solution, we find that there is not closed orbit in this space-time.

Key words: de-Sitter space-time, geodesic, ray trace
