摘要 讨论了一类带有正线性项的混合单调算子,借助迭代技巧得到一个新的不动点定理。 In this paper,a class of mixed monotone operators with postive linear term is discussed.With the aid of iterative technique,a new fixed point theorem is obtained.Finally,the results are applied to investigating the existence of postive almost periodic solutions for a nonlinear intergral equation.
