本文利用作用在Banach空间上的完全连续算子的Krasnosel'skil不动点定理研究了一类非线性二阶差分方程Δ[p(t)Δu(t)]+f(t,u,(t))=0的共轭边值问题,获得了其正解(或负解)存在的充分条件.

In this paper ,by applying Krasnosel＇skii fixed point theorem for completely continuous operator on Banach space ,some sufficient conditions are obtained for the existence of solutions for some conjugate Boundary Value Problems （BVP） of the second-order nonli...
