Fuzzy n-Fold fantastic (implicative, positive implicative) lters in BL-algebras

In this paper, we nd some new results on fuzzy n-fold (positive) implicative lters and n-fold (positive) implicative BL-algebras. Finally, we introduce the concept of fuzzy n- fold fantastic lters and we state and prove some connections between this lters and n- fold (positive) implicative lters.
