On duality theorems for a nondifferentiable minimax fractional programming. (English) Zbl 1010.90080
Summary: The optimality conditions of [{\it H. C. Lai, J. C. Liu} and {\it K. Tanaka}, J. Math. Anal. Appl. 230, No. 2, 311-328 (1999; Zbl 0916.90251)] can be used to construct two kinds of parameter-free dual models of nondifferentiable minimax fractional programming problems which involve pseudo-/quasi-convex functions. In this paper, the weak duality, strong duality, and strict converse duality theorems are established for the two dual models.
