Iteration Method Research for Zero Points of m-accretive Operators in Hilbert Space

摘要/Abstract

摘要:

在Mann的迭代算法基础上,通过引入算子的预解式,将Hilbert空间中求算子的零点问题转化为解算子不动点问题;同时运用距离投影,使每次迭代生成的序列都在一个闭凸的集合中,并证明了修改后的算法的强收敛性.

Abstract:

Based on Mann iteration method,the problem of solving zero points of the operator is converted into the one of solving its fixed points by introducing its resolvent in Hilbert spaces.Meanwhile,the sequence generated by an iteration is located in a closed and convex set by using the metric projection.The strong convergence of the revised method is proved.
