Second order tangency conditions and differential inclusions: a counterexample and a remedy

In this paper we show that second order tangency conditions are superfluous not to say useless while discussing the existence condition for certain second order differential inclusions. In this regard, a counterexample is provided even in the simpler setting of second order differential equation...
