Ekeland’s Variational Principle and Minimization Takahashi’s Theorem in Generalized Metric Spaces
Mathematics, 2018 We consider a distance function on generalized metric spaces and we get a generalization of Ekeland Variational Principle (EVP). Next, we prove that EVP is equivalent to Caristi–Kirk fixed point theorem and minimization Takahashi’s theorem.

A New Variational Inequality with its Application [PDF]
, 2009 In this paper, we suggest the iterative algorithm for a variational inequality by using the auxiliary principle technique, which is closely related to the optimal boundary control of time-varying population system with age-dependence and spatial ...

Ekeland’s variational principle in weak and strong systems of arithmetic [PDF]
, 2020 We analyze Ekeland’s variational principle in the context of reverse mathematics. We find that that the full variational principle is equivalent to Π11- CA0, a strong theory of second-order arithmetic, while natural restrictions (e.g.

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.

Journal of Management Studies, Volume 59, Issue 8, Page 2024-2066, December 2022., 2022 Abstract How and when does engagement with a stigmatized organization lead to the transfer of its stigma to organizations and individuals associating with it? To answer this question, we conduct an inductive study of the process of stigma transfer and the conditions determining social actors’ susceptibility to such courtesy stigma. We build our process

On the demand for telemedicine: Evidence from the COVID‐19 pandemic
Health Economics, Volume 31, Issue 7, Page 1491-1505, July 2022., 2022 Abstract Telemedicine can expand access to health care at relatively low cost. Historically, however, demand for telemedicine has remained low. Using administrative records and a difference‐in‐differences methodology, we estimate the change in demand for telemedicine experienced after the onset of the COVID‐19 epidemic and the imposition of mobility ...

Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022 We are concerned with the following nonlocal problem involving critical Sobolev exponent −a−b∫Ω∇u2dxΔu=λuq−2u+δu2u,x∈Ω,u=0,x∈∂Ω, where Ω is a smooth bounded domain in ℝ4, a, b > 0, 1 < q < 2, δ, and λ are positive parameters. We prove the existence of two positive solutions and obtain uniform estimates of extremal values for the problem.

Abstract and Applied Analysis, Volume 2022, Issue 1, 2022., 2022 In this paper, we establish a generalization of the Galewski‐Rădulescu nonsmooth global implicit function theorem to locally Lipschitz functions defined from infinite dimensional Banach spaces into Euclidean spaces. Moreover, we derive, under suitable conditions, a series of results on the existence, uniqueness, and possible continuity of global ...

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.

Existence of Two Solutions for a Critical Elliptic Problem with Nonlocal Term in ℝ4
Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022 In this paper, we prove the existence of two positive solutions for a critical elliptic problem with nonlocal term and Sobolev exponent in dimension four.
