摘要 定义了b-度量空间中弱压缩映射,证明了由Picard迭代生成的序列强收敛到弱压缩映射的一个不动点.改进和推广了Fat.ma等人的研究结果. In b-metric space,weak constraction was introduced.The sequence generated by picard iterative strongly converge to a fixed point of weak constraction.The result extends and improves the corresponding results announced by Fatma etc.
