In this paper, we propose some dual formulations of generalized vector equilibrium problems. By using such dual formulations, we prove the existence of a solution to the generalized vector equilibrium problem under generalized pseu-domonotonicity conditions. The results of this paper extend and generalize the Ž .
An L(2, 1)-labeling of a graph G is equitable if the number of elements in any two color classes differ by at most one. The equitable L(2, 1)-labeling number λ e (G) of G is the smallest integer k such that G has an equitable L(2, 1)-labeling. Sierpi´nski graphs S(n, k) generalize the Tower of Hanoi graphs — the graph S(n, 3) is isomorphic to the graph of… (More)
