摘　　要：利用正规对偶映射的定义,给出了任意Banach空间Lipschitz强伪压缩映射不动点的Ishikawa迭代收敛定理。该定理不仅推广了已知结果,而且还简化了目前相应结果的证明。In this paper, by virtue of a definition of normalized duality mappings, we give convergence Theorems of Ishikawa iteration of fixed points for strongly pseudocontractive mappings in arbitrary Banach spaces. These Theorems not only extend the known results, but also simplify the identification of the corresponding results.
