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 inflationary phenomenology of a non-minimally coupled Einstein-Gauss-Bonnet gravity theory in the presence of a scalar potential, under the condition that the gravitational wave speed of the primordial gravitational waves is equal to unity, that is c T 2 = 1, in natural units.

TL;DR: In this article, the authors investigated the theoretical implications of the constraint that the graviton is massless to an Einstein-Gauss-Bonnet theory with linear coupling of the scalar field to the four dimensional Gauss invariant.

TL;DR: In this article, the authors demonstrate that it is possible to describe a primordial bounce with the dark energy era in a unified way, in the context of Gauss-Bonnet modified gravity.

TL;DR: In this article, a quantitative approach for extracting predictions on the primordial gravitational wave energy spectrum for $f(R)$ gravity was developed, where two distinct models were carefully chosen in order for them to describe in a unified way inflation and the dark energy era, in both cases viable and compatible with the latest Planck data.
