Higher-order conditions for strict local Pareto minima in terms of generalized lower and upper directional derivatives

摘要

We introduce lower and upper limits of vector-valued functions with respect to the usual positive cone in a finite-dimensional space. Using these concepts, we extend the definitions of. m-th order lower and upper directional derivatives introduced in Studniarski (1986). [1] to vector-valued functions, and prove some necessary and sufficient conditions for strict local Pareto minimizers of order. m.
