我们学习并且在概括非局部的严肃导出精力条件,它是把一个学期加到 Einstein-Hilbert 行动获得的一般相关性的修改理论。而且,在精力条件的意思上获得某卓见,我们为不同 n 与模型参数说明四个精力条件的进化。由分析,我们在模型参数上给限制。
We study and derive the energy conditions in generalized non-local gravity, which is the modified theory of general relativity obtained by adding a term m2n-2R□-nRto the Einstein-Hilbert action. Moreover, to obtain some insight on the meaning of the energy conditions, we illustrate the evolutions of four energy conditions with the model parameter ε for different n. By analysis we give the constraints on the model parameters ε.
