D. V. Luu and P. T. Kien propose in Soochow J. Math. 33 (2007), 17-31, higher-order conditions for strict efficiency of vector optimization problems based on the derivatives introduced by I. Ginchev in Optimization 51 (2002), 47-72. These derivatives are defined for scalar functions and in their...

A multicriteria optimization problem is called Pareto reducible if its weakly efficient solutions are Pareto solutions of the problem itself or a subproblem obtained from it by selecting certain criteria. The aim of this paper is to introduce a similar concept of Pareto reducibility for a class...
