In this paper, given an endomorphism α and a ∨-closed subset S of a BL-algebra, we introduce the concepts of α-prime filters and S-prime filters in BL-algebras, two notions that generalize the prime filters of BL-algebras. We give some examples and examine their first properties and characterizations. Furthermore, we define the notions of α-maximal filters and S-maximal filters of BL-algebras and study the connections among all the introduced classes of filters as well as their relationships with maximal and prime filters of BL-algebras.
