We consider integral functionals F(u) of the calculus of variations over the integral (0,1), where the integrands is a non autonomous function depending on higher order derivatives. We show that the relaxed functional can be written as F(u)+L(u), where L(u) is the Lavrentiev Gap, which is explicitly identified in terms of F.

Abstract

We consider integral functionals F(u) of the calculus of variations over the integral (0,1), where the integrands is a non autonomous function depending on higher order derivatives. We show that the relaxed functional can be written as F(u)+L(u), where L(u) is the Lavrentiev Gap, which is explicitly identified in terms of F.
