Cosmological Analysis of Reconstructed Einstein-Aether Models

Abstract

In this thesis, we reconstruct various solutions for the accelerated universe in the Einstein-Aether theory of gravity. For this purpose, we obtain the effective density and pressure for Einstein-Aether theory. We reconstruct the Einstein-Aether model parameter by comparing its energy density with various holographic dark energy models such as Tsallis, R´enyi and Sharma Mittal holographic dark energy models. For this reconstruction, we use two forms of scale factor, power-law and exponential forms. The cosmological analysis of underlying scenario has been done by exploring different cos mological parameters. This includes equation of state parameter, squared speed of sound and evolutionary equation of state parameter via graphical representation. We obtain some favorable results for some model parametric values
