摘要
运用不动点指数理论,获得二阶离散Neumann边值问题存在正解的最优条件.从而将常微方程中有关非线性Neumann边值问题的结果,推广到离散的情况.
By using the fixed-point index theorem,the optimal conditions of the existence of positive solutions to a class of the second-order discrete Neumann boundary value problems was obtained.It extended the previous results concerning the Neumann boundary value problems in ODE cases to that in the discrete cases.
