Weak ϵϵ-efficiency conditions for multiobjective fractional programming

A general framework for a class of (ρ,η,θ)(ρ,η,θ)-invex functions is developed and then applied to establish some parametric sufficient efficiency conditions for multiobjective fractional programming toward achieving weakly ϵϵ-efficient solutions to multiobjective fractional programming problems. The obtained results are general in nature to the sense of a wider generality and applications to other results on multiobjective fractional programming.
