In this paper, we investigate minimal prime subgroups of an l-group and prove the following results: Let G be an l-group. (1) N ∈Γm(G) , then N= a⊥ iff {PNC} is an inductive set; (2) g ∈ G+ , if g is special and its unique value is an atom, then g⊥∈Γm(G) ;(3) G ∈ Bw,Γ1(G) is atomic iff Γm(G)?Γ1(G) . |
