Weak, strong and converse duality theorems are establishedunder second-order (F, ) convexity/pseudo-convexity assumptions. Special cases arealso discussed to show that this paper extends some known results in the literature. %K symmetric duality %K mixed second-order duality %K second-order (F %K ) convexity/pseudo-convexity %K non-differentiable programming %K cone constraints %U http://www.mijst.mju.ac.th/vol6/356-371.pdf
