Characterizations of the $E$-Benson proper efficiency in vector optimization problems
Kequan Zhao, Xinmin Yang · Numerical Algebra Control and Optimization · 2013
In this paper, under the nearly $E$-subconvexlikeness, some characterizations of the $E$-Benson proper efficiency are established in terms of scalarization, Lagrange multipliers, saddle point criteria and duality for a vector optimization problem with set-valued maps. Our main results generalize and unify some previously known results.
