dc.description.abstractWe revisit the dynamics of a nonminimally coupled scalar field model in case of F(phi) R coupling with F(phi) = 1 - xi phi(2), the potentials V(phi) = V-0(1 + phi(p))(2) and V(phi) = V(0)e(lambda phi 2). We use an autonomous system to bring out new asymptotic regimes, and find stable de-Sitter solution. Under the chosen functional form of F(phi) and steep exponential potentials, a true de-Sitter solution is trivially satisfied for which the equation of state w(phi) similar or equal to -1, the effective gravitational constant G(eff) and field phi are constant that has been missed in the power law case and our previous study.
