The purpose of the paper is to study higher order fractional symmetric duality over arbitrary cones for nondifferentiable Mond-Weir type programs under higher- order K-(C, α, ρ, d)-convexity/pseudoconvexity assumptions. Next, we prove appropriate duality relations under aforesaid assumptions.</p>}, number={1}, journal={Statistics, Optimization & Information Computing}, author={Dubey, Ramu and Deepmala and Mishra , Vishnu Narayan}, year={2020}, month={Feb.}, pages={187-205} }
