Abstract:
In this paper we give a new regularity condition for Fenchel duality concerning convex optimization problems in real linear spaces. Then we prove that this condition is implied by some regularity conditions given so far in the literature for this general class of optimization problems. By giving an appropriate example we show that the new regularity condition is indeed weaker than the aforementioned ones.
