On the absence of duality gap for Lagrange-type functions

Given a generic dual program we discuss the absence of duality gap for a family of Lagrange-type functions. We obtain necessary conditions that become sufficient ones under some additional assumptions. We also give examples of Lagrange-type functions for which this sufficient conditions hold.
