Well posedness in vector optimization problems and vector variational inequalities. (English) Zbl 1119.49025

Summary: We give notions of well posedness for a vector optimization problem and a vector variational inequality of the differential type. First, the basic properties of well-posed vector optimization problems are studied and the case of \(C\)-quasiconvex problems is explored. Further, we investigate the links between the well posedness of a vector optimization problem and of a vector variational inequality. We show that, under the convexity of the objective function \(f\), the two notions coincide. These results extend properties which are well known in scalar optimization.
