**5. Conclusions**

In this paper, we discussed higher-order duality theorems for two types of dual models of nondifferentiable minimax fractional programming problems under strictly pseudo (*<sup>V</sup>*, *α*, *ρ*, *d*)-type-I functions. The question arises as to whether the second/higher-order duality theorems developed in this paper hold for the complex minimax fractional programming problem. This will orient the future task of the authors.
