In the present paper, we apply the fuzzy soft set theory to commutative ideals of BCK-algebras. In fact, the notion of fuzzy soft commutative ideals over BCK-algebras is introduced, and related properties are investigated. Relations between fuzzy soft ideals and fuzzy soft commutative ideals are discussed, and conditions for a fuzzy soft ideal to be a fuzzy soft commutative ideal are provided. The “AND” operation, “extended intersection” and “union” of fuzzy soft (commutative) ideals are studied. Furthermore, characterizations of fuzzy soft (commutative) ideals are considered. 6 2021 6 2021 48 56 10.21833/ijaas-crossmark www.science-gate.com false IASE www.science-gate.com 10.21833/ijaas.2021.06.006 http://www.science-gate.com/IJAAS/2021/V8I6/1021833ijaas202106006.html http://science-gate.com/IJAAS/Articles/2021/2021-8-6/1021833ijaas202106006.pdf
