Optimality and duality in multiobjective fractional programming involving ρ-semilocally type I-preinvex and related functions

[摘要] Optimality conditions are obtained for a nonlinear fractional multiobjective programming problem involving eta-semidifferentiable functions. Also, a general dual is formulated and a duality result is proved using concepts of generalized rho-semilocally type I-preinvex functions. (C) 2007 Elsevier Inc. All rights reserved.
