Abstract:

This paper introduced a new kind of second-order tangent cone, and related second-order tangent derivative, termed as second-order radial composed tangent derivative. Some properties of second-order radial composed tangent derivative and its relationship to second-order composed tangent derivative are discussed. Sufficient and necessary optimality conditions are established respectively for a Benson proper efficient element of set-valued optimization by second-order radial tangent derivative.

Key words: second-order radial composed tangent derivative, set-valued optimization, Benson proper efficient element
