Ekeland’s Variational Principle and Some Related Issues

چکیده
We introduce several new kinds of inferior and superior limits and corresponding kinds of semicontinuity of a set-valued map. Together with the known concepts of semicontinuity, they can be used to have a clearer insight of local behaviors of maps. Then we investigate all major semicontinuity properties of solution maps to a general quasivariational inclusion. Consequences are derived for several particular problems, including some connections to Ekeland’s variational principle.

متن کاملExposita Notes A simple proof of Ekeland and Scheinkman’s result on the necessity of a transversality condition?
Ekeland and Scheinkman (1986) prove the necessity of a standard transversality condition under certain technical conditions. Their result is one of the most powerful on the necessity of a transversality condition currently available in the literature, and their proof involves numerous estimations and relies on Ekeland’s variational principle and Fatou’s lemma. This note relaxes some of their as...
متن کاملSome Generalizations of Caristi’s Fixed Point Theorem with Applications
In this paper, we prove some generalizations of Caristi’s fixed point theorem, and then we give applications to Ekeland’s variational principle and maximal element theorem. Mathematics Subject Classification: 47H10, 54H25
متن کاملA Generalization of Ekeland’s Variational Principle with Applications
In this paper, we establish a variant of Ekeland’s variational principle. This result suggest to introduce a generalization of the famous PalaisSmale condition. An example is provided showing how it is used to give the existence of minimizer for functions for which the Palais-Smale condition and the one introduced by Cerami are not satisfied.
متن کاملEquivalent Extensions to Caristi-Kirk’s Fixed Point Theorem, Ekeland’s Variational Principle, and Takahashi’s Minimization Theorem
With a recent result of Suzuki 2001 we extend Caristi-Kirk’s fixed point theorem, Ekeland’s variational principle, and Takahashi’s minimization theorem in a complete metric space by replacing the distance with a τ-distance. In addition, these extensions are shown to be equivalent. When the τ-distance is l.s.c. in its second variable, they are applicable to establish more equivalent results abou...
