This communication deals with first introducing the exponential type hybrid B-(b,ρ,θ, ṗ,ṙ)-invexities and then establishing a class of the ε-efficiency conditions applying to multiobjective fractional programming problems. The exponential type hybrid B-(b,ρ,θ, ṗ,ṙ)-invexities encompass most of the existing generalized higher order invexities as well as the exponential type generalized invexities, including the Antczak type first order B-(ṗ,ṙ)-invexities. To the best of our knowledge, the obtained results seem to be most advanced on generalized invexities available in the literature, while offer more suitable applications to other fields and beyond.
