ABSTRACT
A notion of generalized weak-subdifferentials for vector functions on a linear space is proposed. Properties of the weak-subdifferentials are investigated. A notion of weak-stability for a nonconvex optimization problems is introduced. Finally, relations between weak-stability and strong duality of the problem are established.
