We consider the following generalized quasi-variational inequality problem introduced in [7]: given a real normed spaceXwith topological dualX*, two setsC,D⊆Xand two multifunctionsS:C→2D andT : C→2X *, find ( x ^ ,   φ ^ ) ∈ C × X * such that x ^ ∈ S ( x ^ ) ,   φ ^ ∈ T ( x ^ )   and   〈 φ ^ , x ^ −...
