Item Mixed Type Duality For Multiobjective Fractional Programming Involving Nonsmooth (F, p)-convex Functions(國立僑生大學先修班, 2003-12-??) J. C. LiuWe restate the necessary optimality conditions of Rcf. 1 to formulate one mixed type dual model for multiobjective fractional programming problems with nonsmooth (F, p)-convex functions. This mixed type dual model unifies Wolfe type dual model and Mond-Weir type dual model. We also establish weak, strong and converse duality theorems.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.
