This paper deals with the super efficient sets in vector optimization of set-valued maps. It is proved that these sets are connected under an assumption of cone-convexlikeness and upper semicontinuity. Copyright Springer-Verlag Berlin Heidelberg 1998

In this paper, an optimal portfolio selection problem is formulated as a minimax problem in which tax and dividend are associated with transactions. The corresponding optimal portfolio is derived respectively in the market with and without riskless asset. Furthermore, the relation and main...

In this paper, we consider a more general form of weak vector variational inequalities and prove some results on the existence of solutions of our new class of weak vector variational inequalities in the setting of Hausdorff topological vector topological space. We also discuss the connectedness...
