| Abstract: | In the paper,we mainly discuss the existence of the eventually positive solution to the second order nonlinear difference equation.On the basis of the Banach contraction mapping principle,we obtain the existence of eventually positive solution of the equation for the four type of distribution situation of the neutral terms system. |
| Keywords: | nonlinear difference equation positive solution neutral term oscillation non-oscillation |
