Vectorial Ekeland Variational Principles: A Hybrid Approach
2015This paper proposes a hybrid approach in establishing vectorial versions of Ekeland’s variational principle. It bases on both the nonlinear scalarization functional in Tammer (Gerth) and Weidner’s nonconvex separation theorem [14] from a scalarization approach and Bao and Mordukhovich’s iterative scheme in [5] from a variational approach.

On the Ekeland variational principle
2011For proper lower semicontinuous functionals bounded from below which do not increase upon polarization, an improved version of Ekeland’s variational principle can be formulated in Banach spaces, which provides almost symmetric ...

The Ekeland’s Principle and the Pareto ε-Efficiency
1996We present in this paper a new variant of Ekeland’s variational principle for vector valued functions with applications to the study of Pareto e-efficiency. A new existence result for Pareto efficiency is also presented.

On a complement to Ekeland's variational principle
1997We give a sufficient condition to a closed convex hull of the set of the Ekeland's points of a certain lower semicontinuous function defined on a real Banach space X coincides with X.
