Fuzzy soft semigroups and fuzzy soft ideals

In this paper, the notions of fuzzy soft semigroup and fuzzy soft (left, right) ideal are given, and the αα-level set, union and intersection of them were studied for each α∈[0,1]α∈[0,1]. Finally, fuzzy soft image and fuzzy soft inverse image of fuzzy soft semigroup (ideal) are discussed.
