Abstract

Since Perlmutter and A.G. Riess (Reiss, Adam G.,1998) observed that the Universe expands with an acceleration, many models involving dark energy have been proposed to explain this phenomenon. (Perlmutter, S., 1997), (Reiss, Adam G., 1998). A family of cosmological models with both acceleration and deceleration is presented in this research study.
