论文摘要
在Noether对称方法的标准下,考虑了非本地重力宇宙学。特别是,我们专注于非本地理论,其重力作用取决于曲率和高斯标量标量不变。相关点状的拉格朗日的特定功能形式是由Noether对称选择的,我们解决了相应的场方程,以发现确切的宇宙学解决方案。
Non-local gravity cosmologies are considered under the standard of Noether Symmetry Approach. In particular, we focus on non-local theories whose gravitational actions depend on curvature and Gauss-Bonnet scalar invariants. Specific functional forms of the related point-like Lagrangians are selected by Noether symmetries and we solve the corresponding field equations finding out exact cosmological solutions.
