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 to reconstruction of Einstein-Aether Gravity from other modified gravities like , , , and and check its viability. The scale factor is chosen in power law form. The free function for Einstein-Aether gravity (where is proportional to ) have been found in terms for by the correspondence between Einstein-Aether gravity and other modified gravities and the nature of vs have been shown graphically for every cases. Finally, we analyzed the stability of each reconstructed Einstein-Aether gravity model.
