摘要
In this paper, we investigate the possibility of obtaining bouncing-oscillating solution in modified Friedmann equations with logarithmic entropy corrected, S = A/4G + alpha In A/4G + beta 4G/A, for positive, negative and zero values of (alpha, beta) pre-factors and all kinds of curved universes. The results are argued using the dynamical system techniques and by employing the phase plane analysis for full classification of the nonsingular evolutions. Our analysis indicates that it is possible to have an oscillating universe as well as a bounce universe for k = 1 and k = -1 curvatures. In k = 1 case, both positive and negative values of alpha and beta can make bouncing-oscillating solution, while ink = -1 case, only the positive value of a with negative value of beta can make a bounce. Also the flat universe have no bounce solution.
