利用b-度量空间中自映象对相容和弱相容条件,讨论了b-度量空间中一类平方型Φ-压缩映象公共不动点的存在性与唯一性问题,证明了一个新的公共不动点定理,改进和推广了某些已知结果.
By using the compatible and weak compatible conditions of self-mapping pair in b-metric spaces,the existence and uniqueness of common fixed point for a class of twice power typeΦ-contractive mappings in b-metric spaces is discussed.A new common fixed theorem is obtained.
