Abstract: In this paper, we introduce a new directional derivative and subgradient of set-valued mappings by using a nonlinear scalarizing function. We obtain some properties of directional derivative and subgradient for cone-convex set-valued mappings. As applications, we present necessary and sufficient optimality conditions for set optimization problems and show that the local weak l-minimal solutions of set optimization problems are the global weak l-minimal solutions of set optimization problems under the assumption that the objective mapping is cone-convex.

Key words: Set optimization problem, Nonlinear scalarizing function, Directional derivative, Subgradient
