Bertrand空间与广义相对论中的投影闭轨
Bertrand Spaces and Projected Closed Orbits in General Relativity
摘要:
通过比较相对论轨道微分方程和相应的经典轨道微分方程,找到了导致投影闭合轨道的度量。这些奇特的时空的物理和几何性质的推导和讨论。它还表明,这些时空中的一些属于更广泛的类的Bertrand时空。
英文摘要:
In the present work, metrics which lead to projected closed orbits are found by comparing the relativistic differential equation of orbits with the corresponding classical differential equation. Physical and geometrical properties of these peculiar spacetimes are derived and discussed. It is also shown that some of these spacetimes belong to the broader class of the Bertrand spacetimes.
