摘　　要：杂交投影算法考虑了具有误差的修正Mann迭代过程,在Hilbert空间的框架下,验证了由该杂交投影算法产生序列的收敛性,并在缺乏紧性的条件下建立了不动点序列的强收敛定理.所得结果改进和推广了近期的一些相应已知结果.In this paper,Mann iterative process with errors is considered based on hybrid projection algorithm.Convergence of iterative sequences generated in the purposed hybrid projection algorithm are obtained.A strong convergence theorem of fixed point sequence is established.The results presented in this paper improve and extend some corresponding known results.
