| Summary: | This article is devoted to discussing the nondifferentiable minimax fractional programming problem with type-I functions. We focus our study on a nondifferentiable minimax fractional programming problem and formulate a higher-order dual model. Next, we establish weak, strong, and strict converse duality theorems under generalized higher-order strictly pseudo <inline-formula> <math display="inline"> <semantics> <mrow> <mo>(</mo> <mi>V</mi> <mo>,</mo> <mi>α</mi> <mo>,</mo> <mi>ρ</mi> <mo>,</mo> <mi>d</mi> <mo>)</mo> </mrow> </semantics> </math> </inline-formula>-type-I functions. In the final section, we turn our focus to study a nondifferentiable unified minimax fractional programming problem and the results obtained in this paper naturally unify. Further, we extend some previously known results on nondifferentiable minimax fractional programming in the literature.
