In this note the notion of interval-valued fuzzy JB-algebras (briefly, i-v fuzzy .B-algebras), the level and strong level B-subalgebra is introduced. Then we state and prove some theorems which determine the relationship between these notions and Z?-subalgebras. The images and inverse images of i-v fuzzy B-subalgebras are defined, and how the homomorphic images and inverse images of i-v fuzzy 23-subalgebra becomes i-v fuzzy i5-algebras are studied.
