On 10/13/16, we proved that if is an open and convex subset of and if is differentiable with for all then we have that for all .

We also proved the analogous statement if is Lipschitz continuous instead of having uniformly bounded derivative.

Lastly, we created a formulation for the problem if is star-shaped rather than convex.
