Ekeland's ε-variational principle for set-valued mappings

Mathematical Methods of Operations Research, 1998
In this paper, we introduce the concept of approximate solutions for set-valued mappings and provide a sufficient condition for the existence of approximate solutions of set-valued mappings. We obtain an approximate variational principle for set-valued mappings.

Vectorial Ekeland Variational Principles: A Hybrid Approach

2015
This 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

2011
For 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 ...
