Inflation Scenario

In this work we investigate which Loop Quantum Cosmology (LQC)-corrected Gauss–Bonnet [Formula: see text] gravity can realize two singular cosmological scenarios, the intermediate inflation and the singular bounce scenarios. The intermediate inflation scenario has a Type III sudden singularity at [Formula: see text], while the singular bounce has a soft Type IV singularity. By using perturbative techniques, we find the holonomy-corrected [Formula: see text] gravities that generate at leading order the aforementioned cosmologies and we also argue that the effect of the holonomy corrections is minor to the power spectrum of the primordial curvature perturbations of the classical theory.

Abstract In this paper, we present the cosmic inflation scenario in some viable models of the f(R) modified gravity of polynomial-exponential form. Results show that the magnitude of the parameter β in these viable models is at the order of 5.67x10–76 and the time of inflation is at the order of 4.6 x 10–35 s.

Inflation Scenario

The relevance of quantum rolling tachyons and corresponding inflation scenario in the frame of the standard, p-adic and adelic cosmology are reviewed. The field theory of tachyon matter proposed by Sen in a zero-dimensional version leads to a number of models with a particle moving under different potentials. We consider quantum propagators of the models, as well as, the vacuum states and conditions necessary to construct an adelic generalization. In addition we present inflationary scenarios for some interesting models based on analytic and numeric calculations. A brief overview of the state of art in the field and suggestions for further consideration close the paper.
