WebOne can also argue without referring to the Hessian (which may fail to exist at some points): the Lipschitz smoothness of f, by your item 1, gives us at every x 0 a quadratic function q so that q ( x 0) = f ( x 0) and f ≤ q everywhere. Taking convex conjugate reverses the order: q ∗ ≤ f ∗; and this means that f ∗ is strongly convex. Question 1.
