On the first page of this article the second sentence of the first paragraph should read “A well-known result in convex analysis says that if f is proper, then f = f ∗∗ if and only if f is a lower semicontinuous and convex function (we recall that a function is proper if it takes values in (−∞, +∞] and is not identically +∞).” The editorial office regrets this omission.
