Abstract
We introduce generalized definitions of Peano and Riemann directional derivatives in order to obtain second-order optimality conditions for vector optimization problems involving
C1,1 data. We show that these conditions are stronger than those in literature obtained by means of second-order Clarke subdifferential.
