摘要

一个简单的非局域德西特引力模型（\(\sqrt{dS}\)）在宇宙和星系尺度上显示出良好的性质。它的宇宙学解与实验数据非常吻合。螺旋星系（银河系和M33）的旋转曲线也可以用\(\sqrt{dS}\)模型很好地描述。本文简要概述了以前的一些结果，包括一个关于寻找具有标量场的宇宙学解的适当局部描述的新结果。Doi 10.1134/ s1061920824601824

Nonlocal de Sitter \(\sqrt{dS}\) Gravity Model and Its Applications

A simple nonlocal de Sitter gravity model (\(\sqrt{dS}\)) 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 \(\sqrt{dS}\) 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.

期刊介绍： Russian Journal of Mathematical Physics is a peer-reviewed periodical that deals with the full range of topics subsumed by that discipline, which lies at the foundation of much of contemporary science. Thus, in addition to mathematical physics per se, the journal coverage includes, but is not limited to, functional analysis, linear and nonlinear partial differential equations, algebras, quantization, quantum field theory, modern differential and algebraic geometry and topology, representations of Lie groups, calculus of variations, asymptotic methods, random process theory, dynamical systems, and control theory.
