摘要 在一实的Banach空间中,引入一修订的有限簇拟压缩映像T1,T2,…,Tm,并证明了在一定条件下,关于{xn}的迭代:xn+1=(1-α1n)xn+α1nT1y1n+u1n,y1n=(1-α2n)xn+α2nT2y2n+u2n…,y(m-1)n=(1-αmn)xn+αmnTmxn+umn,(m≥2)强收敛与有限个似压缩簇T1,T2,…,Tm的公共不动点。本文的结果改进和推广了一些文献的最新结果。 In a solid Banach space,the introduction of a revised limited cluster T1,T2,…,Tm quasi-contractive mapping was done,and proved that under certain conditions,on the{xn}of iterations:xn+1=(1-α1n)xn+α1nT1y1n+u1n,y1n=(1-α2n)xn+α2nT2y2n+u2n…,y(m-1)n=(1-αmn)xn+αmnTmxn+umn,(m≥2)strong convergence in a finite number of clusters to be compression of the common fixed point of T1,T2,…,Tm.The results of this paper improve and generalize of the latest results of the literature.
