Summary: In this paper, a multiobjective fractional subset programming problem (Problem (P)) is considered. A new class of \((\mathcal{F},b,\phi,\rho,\theta)\)-type-I univex function is introduced and a general dual model for (P) is presented. Based on these functions, weak, strong and converse duality theorems are derived. Almost all results presented in the literature were obtained under the assumption that the function \(\mathcal{F}\) is sublinear in the third argument. Here, our results hold assuming only the convexity of this one.
