MULTIOBJECTIVE MIXED SYMMETRIC DUALITY WITH INVEXITY
Izhar Ahmad · 2005
The usual duality results are established for mixed symmetric mul- tiobjective dual programs without nonnegativity constraints using the notion of invexity/ generalized invexity which has allowed weakening various types of convexity/ generalized convexity assumptions. This mixed symmetric dual formulation unies two existing symmetric dual formulations in the literature.
