Abstract In this paper, by using a alternative theorem, we establish Lagrangian conditions and duality results for set-valued vector optimization problems when the objective and constant are nearly ...

AN excellent introduction to the subject of vector analysis is provided by this book. It is admirably clear, and a natural temptation to develop so fertile a theory in excessive detail and to multiply ...

Abstract In this paper, four types of Levitin-Polyak well-posedness of vector quasi-equilibrium problems with a functional constraint, as well as an abstract set constraint are investigated. Some ...
