Abstract
We study the dynamical system of braneworld cosmology with the effective cosmological constant as the effective dark energy on brane universe. Firstly we introduce several scenarios of braneworld model then derive the effective EFE on the brane which reduced at low energy limit. Next, we discuss the FRW cosmological model in braneworld scenario considered in static and non-closed system. In the dynamical study of cosmology, we assume the equation of state of dark energy varies with time and can be parameterized as a function of scale factor of the universe. Using the dynamical system approach, we describe the evolution of brane universe with non-vanishing NCC/BCC term. In this study, we investigate the effects of the presence of NCC/BCC perturbations in brane universe. Finally, we discuss the NCC/BCC perturbations in the late-time cosmic acceleration when the dark energy contribution is ΩΛ ≃ 0.72.
