摘要 对凸度量空间中非线性拟压缩映象具误差的Ishikawa型迭代序列的收敛性问题证明了几个新的收敛性定理 ,结果不仅改进和推广了L .B .Ciric ,Q .H .Liu ,H .E .Rhoades,H .K .Xu等人的相应结果 ,而且对Rhoades_Naimplally_Singh所提出的公开问题 ,在凸度量空间的框架下给出了肯定的答复· Some convergence theorems of Ishikawa type iterative sequence with errors for nonlinear general quasi_contractive mapping in convex metric spaces are proved. The results not only extend and improve the corresponding results of L.B.Ciric, Q.H.Liu, H.E.Rhoades and H.K.Xu, at el but also give an affirmative answer to the open question of Rhoades_Naimpally_Singh in convex metric spaces.
