o:37728 Nonlocal de Sitter √dS Gravity Model and Its Applications en Abstract— A simple nonlocal de Sitter gravity model (√dS) shows good properties on cosmological and galactic scales. Its cosmological solution agrees very well with the experimental data. The rotation curves of spiral galaxies (Milky Way and M33) are also well described by the √dS model. This article contains a brief overview of earlier results, including a new result on finding an appropriate local description with a scalar field for cosmological solutions. 1552099 10.1134/S1061920824601824 1552101 061-9208 2026-02-04T10:25:05.102Z 44 yes 46 Ivan Dimitrijević Faculty of Mathematics, University of Belgrade, Belgrade 0000-0003-3092-2295 Branko Dragovich Institute of Physics, University of Belgrade, Belgrade person 0000-0002-5818-0150 Zoran Rakić Faculty of Mathematics, University of Belgrade, Belgrade, person Jelena Stanković Faculty of Education, University of Belgrade, Belgrade person 0000-0003-2596-7827 application/pdf 562769 https://phaidrabg.bg.ac.rs/o:37728 no yes 1 70 92000001 11A42 Russian Journal of Mathematical Physics 32 1 1 17 2025
