摘要
利用从非对称度量空间(X,d)到(R,dL)上的左K型Lipschitz映射和右K型Lipschitz映射构造了两类非对称度量空间,并分别证明了其上完备性和下完备性.
Based on the left K-Lipschitz mapping and right K-Lipschitz mapping from asymmetric space(X,d) to(R,dL),two types of quasi-metric spaces are structured,and the upper and lower completeness of the two types of asymmetric spaces are proved respectively in this paper.
