Reconstruction of the equation of state for the cyclic universes in homogeneous and isotropic cosmology
Kazuharu Bamba, Kuralay Yesmakhanova, Koblandy Yerzhanov +1
We study the cosmological evolutions of the equation of state (EoS) for the universe in the homogeneous and isotropic Friedmann-Lemaître-Robertson-Walker (FLRW) space-time. In part…
Cosmological evolution of equation of state for dark energy in G-essence models
Kazuharu Bamba, Olga Razina, Koblandy Yerzhanov +1
We explore the cosmological evolution of equation of state (EoS) for dark energy in g-essence models, the action of which is described by a function of both the canonical kinetic t…
Some Models of Cyclic and Knot Universes
K. R. Yesmakhanova, N. A. Myrzakulov, K. K. Yerzhanov +3
In this paper, we obtained a class of oscillatory, cyclic and knot type solutions from the non-linear Friedmann equations. This is performed by choosing specific forms of energy de…
