In this note the notion of interval-valued fuzzy Q S -algebra (briefly, i-v fuzzy Q S -algebra), as well as the i-v level and strong i-v level Q S -subalgebra is introduced. Several theorems which determine the relationship between these notions and Q S -subalgebras are stated and proved. The images and inverse images of i-v fuzzy Q S -subalgebras are defined, and how the homomorphic images and inverse images of an i-v fuzzy Q S -subalgebra become i-v fuzzy Q S -algebras is studied as well.
