Bouncing universe with modified dispersion relation

In this paper, employing the modified dispersion relation, we have derived the general modified Friedmann equations and the corresponding modified entropy relations for the Friedmann-Robertson-Walker (FRW) Universe. In this setup, we find that when the big bounce happens, its energy scale and its corresponding modified entropy behavior are sensitive to the value of k. In contrast to the previous work with k = 0, our work mainly demonstrates that the bouncing behavior for the closed Universe with k = 1 appears at the normal energy limit of the modified dispersion relation introduced, and when bouncing phenomenon is in presence, its modified entropy is just equal to zero. Surprisingly, when k = -1, the bouncing behavior is in absence.
