IN HONOR OF KY FAN

Ekeland's variational principle states that if a Gateaux differentiable Ž . function f has a finite lower bound although it need not attain it , then 5 X Ž .5 for every ⑀ ) 0, there exists some point x such that f x F ⑀. This ⑀ ⑀ Ž . Ž .

## Abstract We extend Ekeland's variational principle to locally complete locally convex spaces. As an application of the extension, we obtain a drop theorem in locally convex spaces which improves the related known result.

In this paper, we discuss the stability of Ekeland's variational principles for vector-valued and set-valued maps when the dominating cone is a closed pointed convex cone whose interior may be empty. We provide a new approach to the study of the stability of Ekeland's variational principles for vect
