Optimality Conditions and Duality in Multiobjective Programming With $(\Phi, \rho)$-Invexity


Massimiliano Ferrara, Maria Viorica Stefanescu




$(\Phi, \rho)$−invexity has recently been introduced with the intent of generalizing invex functions in mathematical programming. Using such conditions we obtain new sufficiency results for optimality in multiobjective programming and extend some classical duality properties.
