In our efforts to prove estimates for the Maxwell constants in convex domains, it turned out that in (piecewise) concave domains interesting new non-standard first Korn inequalities hold.
A special case of these non-standard Korn inequalities has been used by Cedric Villani in his celebrated (fields medal) works. We will discuss a disturbing consequence.
