在拟度量的背景下推广了区间值模糊度量的概念,主要结果如下:(1)给出了区间值模糊拟度量空间等距同构的扩张定理;(2)证明了每个区间值模糊拟度量空间有双完备化且它是唯一达到等距同构的;(3)得到了区间值模糊拟度量空间双完备化的构造方法和区间值模糊拟度量空间可双完备化的等价刻画。
We generalize the notions of interval-valued fuzzy metric in the quasi-metric background. The main results of this paper are:( 1) the isometric extension theorem of interval-valued fuzzy quasi-metric space is given;( 2) it is proved that every interval-valued fuzzy quasi-metric space has bicompletion and is unique up to isometry;( 3) a method to construct the interval-valued fuzzy quasi-metric space bicompletion is given,and a equivalent characterization of interval-value fuzzy quasi-metric spaces is obtained which can be bicompletable.
