宇宙学谱移的解释
Interpretations of Cosmological Spectral Shifts
摘要：
结果表明，对于具有平坦或闭合空间截面的Robertson-Walker模型，所有的宇宙学谱移动都可以归因于非平坦连接（从而间接归因于时空曲率）.对于Robertson-Walker模型的双曲空间部分，它表明，宇宙学谱移唯一分裂成“运动”和“引力”的部分，只要距离很小。对于大的距离，一般不存在这种唯一的分裂。一些常见的，但不正确的断言在文献中关于宇宙学谱移的解释，指出。
英文摘要：
It is shown that for Robertson-Walker models with flat or closed space sections, all of the cosmological spectral shift can be attributed to the non-flat connection (and thus indirectly to space-time curvature). For Robertson-Walker models with hyperbolic space sections, it is shown that cosmological spectral shifts uniquely split up into "kinematic" and "gravitational" parts provided that distances are small. For large distances no such unique split-up exists in general. A number of common, but incorrect assertions in the literature regarding interpretations of cosmological spectral shifts, is pointed out.
