Abstract.
We briefly describe the modified Friedmann equations for Einstein-Aether gravity theory and we find the effective density and pressure. The purpose of our present work is the reconstruction of Einstein-Aether Gravity from other modified gravities like f (T) , f (R) , f (G) , f (R, T) and f (R, G) and check its viability. The scale factor is chosen in power law form. The free function F(K) for Einstein-Aether gravity (where K is proportional to H2) have been found in terms of K by the correspondence between Einstein-Aether gravity and other modified gravities and the nature of F(K) vs. K have been shown graphically for every cases. Finally, we analyzed the stability of each reconstructed Einstein-Aether gravity model.
