摘要:This is a continuation part of our investigation in which the second order nonlinear rational difference equation , , where the parameters and , , , , are positive real numbers and the initial conditions , are nonnegative real numbers such that , is considered. The first part handled the global asymptotic stability of the hyperbolic equilibrium solution of the equation. Our concentration in this part is on the global asymptotic stability of the nonhyperbolic equilibrium solution of the equation.
