二阶非线性差分方程的始终正解的存在性
Existence for Throughout Positive Solution of Second Order Nonlinear Difference Equations
【摘要】 讨论了二阶非线性差分方程始终正解的存在性,通过引进适当的映射,利用Banach压缩映射原理,给出了方程具有某种渐近类型的始终正解存在的充分条件.
【Abstract】 The existence problem of the throughout positive solution for the second order nonlinear neutral self-adjoint difference equation is studied.By introducing suitable mapping and by using Banach contraction mapping principle,we obtain sufficient conditions of the existence behavior for the throughout positive solution with some asymptotic types of this equation.
