HEMIEQUILIBRIUM PROBLEMS

open access: yes, 2004
We consider a new class of equilibrium problems, known as hemiequilibrium problems. Using the auxiliary principle technique, we suggest and analyze a class of iterative algo-rithms for solving hemiequilibrium problems, the convergence of which requires ...

Existence results for Stampachia and Minity type implicit variational inequalities with multivalued valued maps

open access: yes, 2011
[[abstract]]Stampacchia and Minty type generalized implicit variational inequality problems are considered. We extended the notion of dense pseudomonotonicity for multivalued maps and established several existence results for solutions of these problems ...

Weak sharp minima for set-valued vector variational inequalities with an application

open access: yes
In this paper, the notion of weak sharp minima is employed to the investigation of set-valued vector variational inequalities. The gap function [phi]T for set-valued strong vector variational inequalities (for short, SVVI) is proved to be less than the ...

Pseudomonotonicity of an Affine Map and the Two Dimensional Case

open access: yesJournal of Information and Optimization Sciences, 2008
In this paper the pseudomonotonicity of the affine map F(x) = Mx+q on the interior of the positive orthant of Rn is studied. A new characterization is suggested involving the positive and the negative polar of the cone generated by the set W*={z=Mx+q ...

Topological Pseudomonotonicity and Vector Equilibrium Problems

open access: yesJournal of Mathematical Analysis and Applications, 2002
In this paper, we introduce the topological pseudomonotonicity to vector valued bifunctions, and derive some existence results for vector equilibrium problems with the corresponding bifunctions topologically pseudomonotone.

Strong Pseudomonotonicity, Sharp Efficiency and Stability for Parametric Vector Equilibria

open access: yesESAIM: Proceedings and Surveys, 2007
We investigate Hőlder type estimates of solutions to parametric vector equilibrium problems. Our results rely on the notion of strong pseudomonotonicity of the bifunctions defining problems.
