Necessary and suficient optimality conditions are obtained in terms of the right diferentials with respect to an arc of the functions. A dual is formulated and duality results are proved using concepts of locally arcwise connected, locally Q-connected and locally P-connected functionsengtechnical reporthttps://www.ucm.es/icaeopen accessGeneralized convexityFractional programmingOptimality conditionsDualityEconometría (Economía)5302 Econometría
