Abstract: A kind of tangent derivative and the concepts of strong and weak * pseudoconvexity for a set-valued map are introduced.By the standard separation theorems of the convex sets and cones the optimality Fritz John condition of set-valued optimization under Benson proper efficiency is established,its sufficience is discussed. The form of the optimality conditions obtained here completely tally with the classical results when the set-valued map is specialized to be a single-valued map.

Key words: Contingent tangent cone, set-valued map, Benson proper efficiency, Fritz John condition
