Weak injectivity in the category of normal fuzzy hypergroups

Igsung Kim


Based on injectivity, we introduce some definitions in the category NFHG of normal fuzzy hypergroups. And we show that a complete normal fuzzy hypergroup is a weakly injective object in  NFHG. Also we investigate  weak injectivity in the comma category  NFHG/K.
