## On embedding problems of fuzzy number spaces. IV.(English)Zbl 0789.46069

Summary: In this paper, we are going to follow the preceding papers to investigate the embedding problem of fuzzy number space NE$$^ 1$$ by means of a concrete embedding operator. Using the embedding operator, some subclasses of NE$$^ 1$$ and metrics on NE$$^ 1$$ are also investigated.
