Duality in nondifferentiable minimax fractional programming with B-(p, r)-invexity

Abstract In this article, we are concerned with a nondifferentiable minimax fractional programming Airliner problem.We derive the sufficient condition for an optimal solution to the problem and then establish weak, strong, and strict converse duality theorems for the problem SHEA BUTTER OLIVE OIL and its dual problem under B-(p, r)-invexity assumptions.Examples are given to show that B-(p, r)-invex functions are generalization of (p, r)-invex and convex functions AMS Subject Classification: 90C32; 90C46; 49J35.
