H\"older Error Bounds and H\"older Calmness with Applications to Convex Semi-Infinite Optimization [PDF]

open access: yes, 2019
Using techniques of variational analysis, necessary and sufficient subdifferential conditions for H\"older error bounds are investigated and some new estimates for the corresponding modulus are obtained.

On a class of fractional p(., .)-Kirchhoff-Schrödinger system type

open access: yesEuropean 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

open access: yesMathematics, 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.

Ekeland Variational Principle and Some of Its Equivalents on a Weighted Graph, Completeness and the OSC Property

open access: yesAxioms, 2023
We prove a version of the Ekeland Variational Principle (EkVP) in a weighted graph G and its equivalence to Caristi fixed point theorem and to the Takahashi minimization principle.

Nonlinear Versions of a Vector Maximal Principle [PDF]

open access: yes, 2011
Some nonlinear extensions of the vector maximality statement established by Goepfert, Tammer and Zalinescu [Nonl. Anal., 39 (2000), 909-922] are given. Basic instruments for these are the Brezis-Browder ordering principle [Advances Math., 21 (1976), 355 ...

Pareto efficiency for the concave order and multivariate comonotonicity [PDF]

open access: yes, 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 ...
