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.

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

The Multiplicity of Nontrivial Solutions for a New px-Kirchhoff-Type Elliptic Problem
Journal of Function Spaces, 2021 In the paper, we study the existence of weak solutions for a class of new nonlocal problems involving a px-Laplacian operator. By using Ekeland’s variational principle and mountain pass theorem, we prove that the new px-Kirchhoff problem has at least two

Existence of solution for a Kirchhoff type problem involving the fractional p-Laplace operator
Electronic Journal of Qualitative Theory of Differential Equations, 2015 This paper is concerned with the existence of solutions to a Kirchhoff type problem involving the fractional $p$-Laplacian operator. We obtain the existence of solutions by Ekeland's variational principle.

On Ekeland's Variational Principle in Partial Metric Spaces
, 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.

Electronic Journal of Qualitative Theory of Differential Equations, 2023 In this article, multiplicity of nontrivial solutions for an inhomogeneous singular biharmonic equation with Rellich potential are studied. Firstly, a negative energy solution of the studied equations is achieved via the Ekeland's variational principle ...

Maximum principle for near-optimality of stochastic delay control problem
Advances in Difference Equations, 2017 This paper is concerned with near-optimality for stochastic control problems of linear delay systems with convex control domain and controlled diffusion. Necessary and sufficient conditions for a control to be near-optimal are established by Pontryagin’s

A minimization theorem in quasi-metric spaces and its applications
International Journal of Mathematics and Mathematical Sciences, 2002 We prove a new minimization theorem in quasi-metric spaces, which improves the results of Takahashi (1993). Further, this theorem is used to generalize Caristi's fixed point theorem and Ekeland's ϵ-variational principle.

Local completeness, drop theorem and Ekeland's variational principle
, 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.
