  We apply an extended version of the method developed in reference
Int.J.Mod.Phys.D5(1996)71, to derive exact cosmological (flat)
Friedmann-Robertson-Walker solutions in RS2 brane models with a perfect fluid
of ordinary matter plus a scalar field fluid trapped on the brane. We found new
exact solutions, that can serve to unify inflation and quintessence in a common
theoretical framework.
