Title:
"On Lipschitz Regularity of Minimizers of a Calculus of Variations Problem with non Locally
Bounded Lagrangians."
Abstract : We prove that the optimal solutions of a calculus of variations problem are Lipschitz continuous. The result
is obtained without assuming that the domain of the Lagrangian is the whole space as usually stated
in the literature. So, the contribution of this note is in giving a new sufficient condition for
non existence of Lavrentiev phenomenon.
