摘要
E是2-一致光滑一致凸的Banach空间,C是E中的闭凸子集,T:C→C为λ-严格伪压缩映像.通过讨论修正的Mann迭代x1∈C,xn+1=(1-αn)xn+αnTnxn,n≥1.当{αn}满足适当的条件,{xn}弱收敛于T的某个不动点,这个结果推广了目前的已知结论.
Let C be a closed convex subset of a 2-uniformly smooth Banach space E which is uniformly convex and assume that T is a λ- strict pseudo-contraction on C . The modified Mann's iteration generated a sequence { xn } by the formula x1∈C,xa+1+(1-αn)xn+αnT^nxn,n≥1 It is proved if c^n satisfy appropriate conditions , then the {xn} converges weakly to a fixed point T. Some vailable results are improved and generalized.
