Abstract

In Brans–Dicke gravitational theory, an analytical accelerating expansion solution of the Universe is found at the dilaton dominated epoch. Both Einstein frame (EF) and Jordan frame (JF) are applied. We consider the form of exponential potential of dilaton field in EF while we consider the power law potential in JF. In matter and dilaton coexisting epoch, only the decelerating expansion solution without potential is considered with experimental constraint α2<0.001. If the power law potential of dilaton field is applied in JF, some authors found the dilaton field can act as quintessence based numerical method.1 We find that the influence of dilaton will not change the evolutionary law of density perturbation of baryon matter.
