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…
On the Schwarzschild-de Sitter metric of nonlocal de Sitter gravity
I. Dimitrijevic, B. Dragovich, Z. Rakic +1
Earlier constructed a simple nonlocal de Sitter gravity model has a cosmological solution in a very good agreement with astronomical observations. In this paper, we continue the in…
Nonlocal de Sitter gravity and its exact cosmological solutions
Ivan Dimitrijevic, Branko Dragovich, Zoran Rakic +1
This paper is devoted to a simple nonlocal de Sitter gravity model and its exact vacuum cosmological solutions. In the Einstein-Hilbert action with term, we introduce nonlocali…
New Cosmological Solutions of a Nonlocal Gravity Model
Ivan Dimitrijevic, Branko Dragovich, Zoran Rakic +1
A nonlocal gravity model (2.1) was introduced and considered recently [49], and two exact cosmological solutions in flat space were presented. The first solution is related to some…
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}\…

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…
New Cosmological Solutions in Nonlocal Modified Gravity
I. Dimitrijevic, B. Dragovich, J. Grujic +1
We consider some cosmological aspects of nonlocal modified gravity with term, where nonlocality is of the type . Using ansatz of the form $\Box R = r R +…
