Pareto efficiency for the concave order and multivariate comonotonicity [PDF]
, 2011 In this paper, we focus on efficient risk-sharing rules for the concave dominance order. For a univariate risk, it follows from a comonotone dominance principle, due to Landsberger and Meilijson [25], that efficiency is characterized by a comonotonicity ...

On an elliptic system of p(x)-Kirchhoff-type under neumann boundary condition
Mathematical Modelling and Analysis, 2012 In the present paper, by using the direct variational method and the Ekeland variational principle, we study the existence of solutions for an elliptic system of p(x)-Kirchhoff-type under Neumann boundary condition and show the existence of a weak ...

On a class of fractional p(., .)-Kirchhoff-Schrödinger system type
European Journal of Mathematics and Applications, 2023 In the present article, we study the existence of a weak solution to an elliptic system of Kirchhoff-Shrodinger type, driven by the fractional $p(.,.)$-Laplacian operator.

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.
