标题： Rotation in relativity and the propagation of light

摘要： 我们比较和对比了Mach、Thirring和Lense以及Goedel在广义相对论中关于旋转的不同观点。 我们的分析依赖于两个工具：(i) Sagnac效应，它允许我们测量坐标系的旋转或由时空曲率引起的旋转，以及(ii)计算机可视化，它揭示了Goedel宇宙的异域特征。 为了保持论文的自包含性，我们在多个附录中总结了广义相对论中使用的数学工具的关键要素。 这样，我们的讲义应该对熟悉张量计算和广义相对论基本要素的研究人员具有可访问性。 显示英文摘要

摘要： We compare and contrast the different points of view of rotation in general relativity, put forward by Mach, Thirring and Lense, and Goedel. Our analysis relies on two tools: (i) the Sagnac effect which allows us to measure rotations of a coordinate system or induced by the curvature of spacetime, and (ii) computer visualizations which bring out the alien features of the Goedel Universe. In order to keep the paper self-contained, we summarize in several appendices crucial ingredients of the mathematical tools used in general relativity. In this way, our lecture notes should be accessible to researchers familiar with the basic elements of tensor calculus and general relativity.
