The Iteration Scheme with Errors for Zero Point of Maximal Monotone Operator in Hilbert Space

摘要/Abstract

摘要:

H为Hilbert空间,A:H→2H为极大单调算子,受Wittmann和Mann对非扩展映射不动点存在性研究方法的启发,把Mann迭代和Rockafellar提出的近似邻近点算法揉和在一起,引进了2种带误差项的迭代格式.分别证明了一种迭代格式强收敛于极大单调算子的零点;另一种弱收敛于极大单调算子的零点.

Abstract:

Let H be a Hilbert space,H→2H be a maximal monotone operator.It is motivated by the iterative methods for finding the fixed points of non-expansive mappings studied by Mann and Wittmann.Two new iterative algorithms with errors of approximating zero points of maximal monotone operators are given by combining the ideas of Mann's iteration and proximal point iteration.One of the algorithms is proved to be strongly convergent to the zero point of maximal monotone operator and the other is proved to be weakly convergent to it.
