Interval-Valued Fuzzy BF-Algebras
Azadeh Alsadat Emrani Zarandi, Arsham Borumand Saeid · 2009
In this note the notion of interval-valued fuzzy BF-algebras (briefly, i-v fuzzy BF-algebras), the level and strong level BF-subalgebra is introduced. Then we state and prove some theorems which determine the relationship between these notions and BF-subalgebras. The images and inverse images of i-v fuzzy BF-subalgebras are defined, and how the homomorphic images and inverse images of i-v fuzzy BF-subalgebra becomes i-v fuzzy BF-algebras are studied.
