Naslov predavanja: SOME COSMOLOGICAL SOLUTIONS IN NONLOCAL MODIFIED GRAVITY

Apstrakt:
We consider model of nonlocal gravity, given by the following action $S = frac{1}{16 pi G} int sqrt{R-2Lambda} F(Box) sqrt{R-2Lambda}sqrt{-g} d^{4}x + matcal{L}_{matter}$, where $ F(Box)= sum_{n=-1}^{infty} f_{n} Box^{n}$. The corresponding equations of motion are presented. Using linear ansatze we derive cosmological solutions with and without matter.
