Duality for a class of symmetric nondifferentiable multiobjective fractional variational problems with generalized (F,α,ρ,d)-convexity

A pair of nondifferentiable symmetric dual problems for a class of multiobjective fractional variational programs over arbitrary cones is formulated. Weak, strong and converse duality relations are then proved under generalized (F,α,ρ,d)-convexity assumptions.
