Abstract:

We give some new regularity conditions for convex optimization problems in separated locally convex spaces which completely characterize the stable strong and strong Lagrange duality and, respectively, the stable strong and strong Lagrange duality for the case when a solution of the primal problem is assumed as known, situations named here total and, respectively, stable total duality. In particular instances the conditions we consider turn into some other constraint qualifications known in the literature, like dual CQ, Farkas-Minkowski CQ, locally Farkas-Minkowski CQ and basic CQ. We show that our new results extend some existing ones in the literature.
