如何在二维de Sitter流形的一部分中引入世界时
How to Introduce A World Time to A Part of Two Dimensional de Sitter Manifold
摘要：
本文定义了1+1维de Sitter流形，并考虑了其上的各种坐标系，利用所考虑的坐标系之间的变换，证明了广义相对论的一些有趣的方面。这个问题可能是感兴趣的物理和数学的学生以及物理教师。
英文摘要：
We define 1+1 dimensional de Sitter manifold in this paper and we consider various coordinate systems on it. Some interesting aspects of the general theory of relativity are demonstrated by using the transformations between the considered coordinate systems. The problem might be of interest for physics and mathematics students as well as for physics teachers.
