Item Sufficiency Criteria And Duality For Complex Nondifferentiable Fractional Programming Involving Pseudoinvex Function(國立僑生大學先修班, 1998-07-??) 劉正傳; 林世昌; J. C. Liu; S. C. LinUnder different forms of invexity conditions, sufficient conditions and five duality models are presented for the nondifferentiable fractional programming problem containing square roots of positive semidefinite Hermitian quadratic forms.Item On Mixed Duality in Multiobjective Fractional Programming Involving Nonsmooth Pseudoinvex Functions(國立僑生大學先修班, 2005-12-??) 劉正傳; J.C.LiuIn this paper, we formulate one mixed type dual model to unify Wolfe type dual and Mond-Weir type dual for multiobjective fractional programming problem with nonsmooth pseudoinvex functions. We also establish weak, strong and strict converse duality theorems.
