Sufficiency and duality for nonsmooth multiobjective programming problems involving generalized (F,α,ρ,θ)-d-V-univex functions

In this paper, we introduce a new class of generalized (F,α,ρ,θ)-d-V-univex functions for a nonsmooth multiobjective programming problem. Sufficient optimality conditions under generalized (F,α,ρ,θ)-d-V-univex functions are established for a feasible solution to be an efficient solution. Appropriate duality theorems for a Mond-Weir-type dual are also presented under the aforesaid assumptions.
