Connectedness and Compactness of Weak Efficient Solutions for Set-Valued Vector Equilibrium Problems
Chen Bin, Xun-Hua Gong, Yuan Shu-min · Journal of Inequalities and Applications · 2008
We study the set-valued vector equilibrium problems and the set-valued vector Hartman-Stampacchia variational inequalities. We prove the existence of solutions of the two problems. In addition, we prove the connectedness and the compactness of solutions of the two problems in normed linear space.
