一致光滑Banach空间中φ-半压缩映象不动点的Noor迭代逼近
Noor Iterative Approximation of Fixed Points for (?) -Hemicontrative Mappings in Uniformly Smooth Banach Spaces
【摘要】 设X是实一致光滑Banach空间,K是X的非空凸有界子集,T:K→K是φ-半压缩映象。{αn}n≥0,{βn}n≥0,{γn}n≥0是[0,1]中的实数列满足如下条件: ①αn→0,βn→0,γn→0(n→∞) ②sum from n=0 αn(1-αn)=∞ 则对任意的x0∈K,由Noor迭代过程 zn=(1-γn)xn+γnTxn,yn=(1-βn)xn+βnTz,xn+1=(1-αn)xn+αnTyn,n≥0所产生的序列{xn}n≥0,强收敛于T的唯一不动点。相关结果处理了关于φ-强拟增生算子的非线性方程的迭代解。

Let {αn}n≥0, {βn }n≥0, and {γn}n≥0 be real sequences in [0,1] satisfying the following conditions :Then, for arbitrary initial value x0∈K, the Noor iterative process {xn}n≥0generated by (N)converges strongly to theunique fixed point of T.A related result deals with the iterative solutions of nonlinear equations involving (?) -strongly quasi-accretive operators.
