The periodic universe with varying deceleration parameter of the second degree

In the present paper, we propose a new law for the deceleration parameter of the second degree of the time. Our law tells us about the behavior of the universe. According to our law, the spatially closed, flat and open universes are allowed, and the universe passes through with a big-rip and then retreats as it was in the moment of the big bang. The law we suggest covers the law of Berman, where the deceleration parameter is constant, also covers the law of the deceleration parameter of the first degree of time obtained by Akarsu and Tekin.
