Inverse Symmetric Inflationary Attractors
S. D. Odintsov, V. K. Oikonomou
We present a class of inflationary potentials which are invariant under a special symmetry, which depends on the parameters of the models. As we show, in certain limiting cases, th…
Viable Mimetic Completion of Unified Inflation-Dark Energy Evolution in Modified Gravity
S. Nojiri, S. D. Odintsov, V. K. Oikonomou
In this paper, we demonstrate that a unified description of early and late-time acceleration is possible in the context of mimetic gravity. We study the inflationary era in…
Newton law in covariant unimodular gravity
S. Nojiri, S. D. Odintsov, V. K. Oikonomou
We propose a covariant ghost-free unimodular gravity theory, which contains a three-form field and study its structure using the analogy of the proposed theory with a quantu…
Correspondence of Gravity Singularities in Jordan and Einstein Frames
Sebastian Bahamonde, S. D. Odintsov, V. K. Oikonomou +1
We study the finite time singularity correspondence between the Jordan and Einstein frames for various gravity theories. Particularly we investigate the ordinary pure …
Singular Cosmology Unifying Early and Late-time Acceleration with Matter and Radiation Domination Era
S. D. Odintsov, V. K. Oikonomou
We present some cosmological models which unify the late and early-time acceleration eras with the radiation and the matter domination era, and we realize the cosmological models b…
Unimodular-Mimetic Cosmology
S. Nojiri, S. D. Odintsov, V. K. Oikonomou
We combine the unimodular gravity and mimetic gravity theories into a unified theoretical framework, which is proposed to provide a suggestive proposal for a framework that may ass…
