In this paper, we establish a sufficient optimality theorem for multiobjective variational problems under generalized invexity conditions. Using the equivalence relation of Weir and Mond, and the concept of proper efficiency, we study Wolfe type duals for multiobjective variational problems under pre-invexity and generalized invexity conditions on the functions.
