Iterative Process to φ-Hemicontractive Operator and φ-Strongly Accretive Operator Equations

  • 摘要:E是任意实Banach空间,K是E的非空闭凸子集.T:K→K是一致连续φ-半压缩映像且值域有界.设{an},{bn},{cn},{a'n},{b'n}和{c'n}是[0,1]中的序列且满足条件:ⅰ)an+bn+cn=a'n+b'n+c'n=1,∀n≥0; 对任意给定的x0,u0,v0∈K,定义Ishikawa迭代{xn}如下:,其中un和vnK中两个有界序列.则xn强收敛于T的唯一不动点.最后研究了φ-强增殖算子方程解的Ishikawa迭代收敛性.
