Maji et al. introduced the concept of fuzzy soft sets as a generalization of the standard soft sets and presented an application of fuzzy soft sets in a decision making problem. In this paper, we apply fuzzy soft sets to - hyperrings. The concept of ( , q ) -fuzzy soft -hyperideals of -hyperrings is first introduced. Some new characterizations are investigated. In particular, a kind of new -hyperrings by congruence relations is obtained.
