Fractional Action Cosmology with Power Law Weight Function
Mubasher Jamil, Muneer A. Rashid, D. Momeni +2
Motivated by an earlier work on fractional-action cosmology with a periodic weight function [1], we extend it by choosing a power-law weight function in the action. In this approac…
FRW cosmological models with integrable and nonintegrable differential equations of state
Shynaray Myrzakul, Kuralay Esmakhanova, Kairat Myrzakulov +2
The basic models of modern cosmology work in FRW spacetime. Hence follows that it is important to study the physical and mathematical nature of FRW cosmological models. In this wor…
Some cosmological aspects of Horava-Lifshitz gravity: integrable and nonintegrable models
G. N. Nugmanova, Sh. R. Myrzakul, O. V. Razina +3
In this work, some new integrable and nonintegrable cosmological models of the Hoava-Lifshitz gravity are proposed. For some of them, exact solutions are presented. Then…
Reconstruction of f-essence and fermionic Chaplygin gas models of dark energy
P. Tsyba, K. Yerzhanov, K. Esmakhanova +3
Recently, it was proposed a new fermionic model of dark energy, the so-called f-essence. In this work, we explicitly reconstruct the different f-essence models. In particular, thes…
Dark energy in some integrable and nonintegrable FRW cosmological models
Kuralay Esmakhanova, Nurgissa Myrzakulov, Gulgasyl Nugmanova +3
One of the greatest challenges in cosmology today is to determine the nature of dark energy, the sourse of the observed present acceleration of the Universe. Besides the vacuum ene…
A note on the relationship between solutions of Einstein, Ramanujan and Chazy equations
Kuralay Esmakhanova, Yerlan Myrzakulov, Gulgasyl Nugmanova +1
The Einstein equation for the Friedmann-Robertson-Walker metric plays a fundamental role in cosmology. The direct search of the exact solutions of the Einstein equation even in thi…
