Abstract
In the present paper, second order duality for multiobjective non-linear programming are investigated under the second order generalized (F, b, phi, rho, theta) - univex functions. The weak, strong and converse duality theorems are proved. Further, we also illustrated an example of (F, b, phi, rho, theta) - univex functions. Results obtained in this paper extend some previously known results of multiobjective nonlinear programming in the literature.
