Duality for multiobjective fractional programming problem using convexifactors

In this paper, the concept of *-quasiconvexity is introduced by using convexifactors. Mond-Weir-type and Schaible-type duals are associated with a multiobjective fractional programming problem, and various duality results are established under the assumptions of *-pseudoconvexity and *-quasiconvexity.
