Abstract

We consider a new modified gravity model with nonlocal term of the form R−1F(□)R. This kind of nonlocality is motivated by investigation of applicability of a few unusual ansatze to obtain some exact cosmological solutions. In particular, we find attractive and useful quadratic ansatz □R = qR2.
一个新的非局部修正引力模型
我们考虑了一个新的修正重力模型,其非局部项为R−1F(□)R。这种非定域性的产生是由于对一些不寻常解的适用性的研究,以获得一些精确的宇宙学解。特别地,我们发现了吸引人的和有用的二次方差□R = qR2。
