Formalizing Anisotropic Inflation in Modified Gravity
S. Nojiri, S. D. Odintsov, V. K. Oikonomou +1
Motivated by the fact that the pre-inflationary era may evolve in an exotic way, in this work we formalize anisotropic evolution in the context of modified gravity, focusing on pre…
Generalized -attractor Cosmology in the Jordan and Einstein Frames: New Type of Attractors and Revisiting Standard Jordan Frame Inflation
S. D. Odintsov, V. K. Oikonomou
In this work we shall study a new class of attractor models which we shall call generalized -attractor models. This class of models is based on a generalization of the Einstei…
Running of the Spectral Index and Inflationary Dynamics of Gravity
S. D. Odintsov, V. K. Oikonomou
In this work we shall provide a model-independent general calculation of the running of the spectral index for vacuum gravities. We shall exploit the functional form of the…
Integral Gravity and Saddle Point Condition as a Remedy for the -tension
S. Nojiri, S. D. Odintsov, V. K. Oikonomou
In this work, we shall provide an gravity theoretical framework for solving the -tension. Specifically, by exploiting the gravity correspondence with a scalar-te…
Chirality of Gravitational Waves in Chern-Simons Gravity Cosmology
S. D. Odintsov, V. K. Oikonomou
In this paper we shall consider an axionic Chern-Simons corrected gravity theoretical framework, and we shall study the chirality of the generated primordial gravitational w…
Anisotropic compact stars in limit of Gauss-Bonnet gravity
G. G. L. Nashed, S. D. Odintsov, V. K. Oikonomou
In the frame of Gauss-Bonnet gravity and in the limit of , based on the fact that spherically symmetric solution derived using any of regularization schemes will be the sam…
