Variations of Infinite Derivative Modified Gravity
Ivan Dimitrijevic, Branko Dragovich, Zoran Rakic +1
We consider nonlocal modified Einstein gravity without matter, where nonlocal term has the form . For this model, in this paper we give the derivation of the equ…
On Nonlocal Modified Gravity and its Cosmological Solutions
Ivan Dimitrijevic, Branko Dragovich, Jelena Stankovic +2
During hundred years of General Relativity (GR), many significant gravitational phenomena have been predicted and discovered. General Relativity is still the best theory of gravity…
Cosmology of non-local f(R) gravity
I. Dimitrijevic, B. Dragovich, A. S. Koshelev +2
We consider a modification of GR with a special type of a non-local f(R). The structure of the non-local operators is motivated by the string field theory and p-adic string theory.…
Some Cosmological Solutions of a Nonlocal Modified Gravity
Ivan Dimitrijevic, Branko Dragovich, Jelena Grujic +1
We consider nonlocal modification of the Einstein theory of gravity in framework of the pseudo-Riemannian geometry. The nonlocal term has the form $\mathcal{H}(R) \mathcal{F}(\Box)…
A New Model of Nonlocal Modified Gravity
Ivan Dimitrijevic, Branko Dragovich, Jelena Grujic +1
We consider a new modified gravity model with nonlocal term of the form This kind of nonlocality is motivated by investigation of applicability of a…
On Modified Gravity
Ivan Dimitrijevic, Branko Dragovich, Jelena Grujic +1
We consider some aspects of nonlocal modified gravity, where nonlocality is of the type . In particular, using ansatz of the form we find a…
