A generalization of Ekeland's variational principle with applications
Electronic Journal of Differential Equations, 2006 In this paper, we establish a variant of Ekeland's variational principle. This result suggest to introduce a generalization of the famous Palais-Smale condition.

On Ekeland's Variational Principle in Partial Metric Spaces [PDF]
, 2015 In this paper, lower semi-continuous functions are used to extend Ekeland's variational principle to the class of partial metric spaces. As consequences of our results, we obtain some fixed point theorems of Caristi and Clarke types.

Bundling and nonlinear pricing in telecommunications
The RAND Journal of Economics, Volume 54, Issue 2, Page 268-298, Summer 2023., 2023 Abstract I develop a multiproduct nonlinear pricing model where a firm sells both discrete and continuous services to consumers with multidimensional heterogeneity. I derive the optimal selling mechanism and provide primitive conditions under which different bundling strategies arise. Exploiting both the firm and the consumer's optimality conditions, I

Parametric Ekeland's variational principle [PDF]
, 2001 A parametrized version of Ekeland's variational principle is proved, showing that under suitable conditions, the minimum point of the perturbed function can be chosen to depend continuously on a parameter.

Generalized Ekeland’s variational principle with applications
Journal of Inequalities and Applications, 2019 By using the concept of Γ-distance, we prove EVP (Ekeland’s variational principle) on quasi-F-metric (q-F-m) spaces. We apply EVP to get the existence of the solution to EP (equilibrium problem) in complete q-F-m spaces with Γ-distances.

Journal of Applied Mathematics, Volume 2023, Issue 1, 2023., 2023 In this article, we deal with the nonlocal elliptic problems of the Kirchhoff type involving the Hardy potential and critical nonlinearity on a bounded domain in R3. Under an appropriate condition on the nonhomogeneous term and using variational methods, we obtain two distinct solutions.

Local completeness, drop theorem and Ekeland's variational principle [PDF]
, 2005 By using a very general drop theorem in locally convex spaces we obtain some extended versions of Ekeland's variational principle, which only need assume local completeness of some related sets and improve Hamel's recent results.

Critical Fractional p‐Laplacian System with Negative Exponents
Journal of Function Spaces, Volume 2023, Issue 1, 2023., 2023 In this paper, we consider a class of fractional p‐Laplacian problems with critical and negative exponents. By decomposition of the Nehari manifold, the existence and multiplicity of nontrivial solutions for the above problems are established with respect to a sufficiently small parameter.

Ekeland's variational principle in locally convex spaces and the density of extremal points [PDF]
, 2009 In this paper, we prove a general version of Ekeland's variational principle in locally convex spaces, where perturbations contain subadditive functions of topology generating seminorms and nonincreasing functions of the objective function. From this, we
