论文摘要
在Friedmann-Lema-Robertson-Walker宇宙学中，有时可以计算分析回顾的时间，宇宙年龄以及光度距离与RedShift相比，以有限数量的基本功能来表达它们。我们使用集成和提供示例的Chebyshev定理对这些情况进行了分类。
In Friedmann-Lemaître-Robertson-Walker cosmology, it is sometimes possible to compute analytically lookback time, age of the universe, and luminosity distance versus redshift, expressing them in terms of a finite number of elementary functions. We classify these situations using the Chebyshev theorem of integration and providing examples.
