Fuzzy strong implicative hyper BCK-ideals of hyper BCK-algebras

摘要

The fuzzy setting of strong implicative hyper BCK-ideals in hyper BCK-algebras is considered, some of their properties are investigated. Relations among fuzzy strong hyper BCK-ideals, fuzzy implicative hyper BCK-ideals, and fuzzy strong implicative hyper BCK-ideals are given. A characterization of a fuzzy strong implicative hyper BCK-ideal is provided. The hyper homomorphic preimage of a fuzzy strong implicative hyper BCK-ideal is discussed. (C) 2004 Elsevier Inc.
