摘要
文章借助于对偶映射的定义,给出了任意Banach空间中LipschitzΦ-强伪压缩映射不动点的Ishikawa迭代收敛定理的简化证明,并且推广了目前相应的已知结果.
By virtue of definition of duality mapping, we give a brief proof for Ishikawa iterative approximation for fixed point of Ф-strongly pseudocontractive mappings in arbitrary Banach spaces, and extend the recent corresponding known results.
