520 3 |a In this paper, we show that (1) for each QFS-domain L, L is an ωQFS-domain iff L has a countable base for the Scott topology; (2) the Scott-continuous retracts of QFS-domains are QFS-domains; (3) for a quasicontinuous domain L, L is Lawson compact iff L is a finitely generated upper set and for any x 1, x 2 ∈ L and finite G 1, G 2 ⊆ L with G 1 ≪ x 1, G 2 ≪ x 2, there is a finite subset F ⊆ L such that ↑ x 1∩ ↑ x 2 ⊆↑ F ⊆↑ G 1∩ ↑ G 2; (4) L is a QFS-domain iff L is a quasicontinuous domain and given any finitely many pairs {(F i , x i ): F i is finite, x i ∈ L with F i ≪ x i , 1 ≤ i ≤ n}, there is a quasi-finitely separating function δ on L such that F i ≪ δ(x i ) ≪ x i .
