The equation of state parameter shows the different stages of the evolution of the Universe for the considered models. By analyzing the cosmological plane ω d –ω d ′ , we obtain the freezing region for these models. Also, due to the study of squared speed of sound, we show the ...
The dark energy is considered as the linear (Model I) and CPL (Model II) parameterizations of the equation of state parameter. For both models, we express the Hubble parameter H (z) in terms of the model parameters and redshift z. To rigorously con- strain the model, we have employed ...
pathed,theassumptions made for imaging data in the offset domain are violated. This will especially in,uence the quality of common image gathers,and hence make it dif,cult to perform any form of AVO or differential semblance based velocity analysis (Symes& ...
The equation of state parameter provides the phantom phase of the universe, while the deceleration parameter illustrates the accelerated phase of the universe. On the other hand, we plot the squared speed of sound and find the positive behavior which ensures the stability of underlying model. More...
We derive the evolutionary form of the fractional energy densities of DE, DM and curvature \\(\\Omega_{D}'\\), \\(\\Omega_{m}'\\) and \\(\\Omega_{k}'\\), the pressure of DE pD, the Equation-of-State (EoS) parameter of DE \\(\\omega_{D}\\) and the deceleration ...
The cosmological parameters include the Hubble parameter, equation of state parameter for the accelerating/decelerating phases, deceleration parameter to explore the expansion rate and squared speed of sound for stability analysis.The Sixteenth Marcel Grossmann Meeting on Recent Developments in Theoretical ...

Solving this equation for t, we obtain four different solutions, among which three do not satisfy the observational bounds for 𝜂𝐵𝑆ηBS and look like extraneous roots of the model. The only solution of Equation (20), which gives good results for 𝜂𝐵𝑆ηBS, is given by 𝑡...
