Abstract: Despite of some significant phenomenological successes and many nice theoretical properties, General relativity (GR) is not complete theory of gravity. Hence, there are many attempts to modify GR. One of promising modern approaches towards more complete theory of gravity is nonlocal modification of GR. Our nonlocal gravity model is given by the action (without matter) $S = \frac{1}{16 \pi G}\int \sqrt{-g} (R - 2\Lambda + P(R) \mathcal{F}(\Box) Q(R)) d^4x ,$ where Language: English |
