On a nonlocal de Sitter gravity
Ivan Dimitrijevic, Branko Dragovich, Zoran Rakic +1
In this paper, we briefly review highlights of nonlocal de Sitter gravity based on the nonlocal term in the Einstein-Hilbert acti…
Some exact anisotropic cosmological solutions of a simple nonlocal de Sitter gravity
Ivan Dimitrijevic
It was shown recently that a very simple nonlocal de Sitter gravity model contains exact vacuum cosmological solution which mimics dark energy and dark matter in flat space. Some o…
Some Cosmological Solutions of a New Nonlocal Gravity Model
I. Dimitrijevic, B. Dragovich, A. S. Koshelev +2
In this paper, we investigate a nonlocal modification of general relativity (GR) with action $S = \frac{1}{16πG} \int [ R- 2Λ+ (R-4Λ) \, \mathcal{F}(\Box) \, (R-4Λ) ] \, \sqrt{-g}\…
Cosmological Solutions of a Nonlocal Square Root Gravity
I. Dimitrijevic, B. Dragovich, A. S. Koshelev +2
In this paper we consider modification of general relativity extending by nonlocal term of the form where $\mathcal{F}(\…
Cosmological solutions in modified gravity with monomial nonlocality
Ivan Dimitrijevic
We consider cosmological properties of modified gravity with nonlocal term in its Lagrangian. Equations of motion are presented. For the flat FLRW metric…
