Strong pseudomonotonicity, sharp efficiency and stability for parametric vector equilibria
Systems Research Institute PAS, Newelska 6, 01-447 Warsaw, Poland
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. When applied to vector optimization problems, the strong pseudomonotonicity introduced in the present paper implies the uniform (with the same constant) sharpness of solutions.
Key words: Parametric vector equilibrium problems / Hőlder continuity / pseudomonotone bifunctions / sharp solutions
