TL;DR: In this paper, the authors systematically review some standard issues and also the latest developments of modified gravity in cosmology, emphasizing on inflation, bouncing cosmology and late-time acceleration era.

TL;DR: In this paper, a new theoretical framework for the Einstein-Gauss-Bonnet theories of gravity is introduced, which results to particularly elegant, functionally simple and transparent gravitational equations of motion, slow-roll indices and the corresponding observational indices.

TL;DR: In this paper, the authors investigate how to describe in a unified way a constant-roll inflationary era with a dark energy era, by using the theoretical framework of F (R ) gravity.

TL;DR: In this article, the slow-roll indices and the observational indices are expressed as functions of the scalar field and the SWAMPLAND criteria are investigated for the Einstein-Gauss-Bonnet theory.

TL;DR: In this article, the authors studied the singularity correspondence between the Jordan and Einstein frames for various F(R) gravity theories, in the absence of any matter fluids, and showed that it is possible to have various correspondences of finite time singularities, and that a singular cosmology in one frame might be non-singular in another frame.
