How to Introduce A World Time to A Part of Two Dimensional de Sitter Manifold
arXiv:physics/0107074
Abstract
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.
