Abstract:

In this paper we study the lower semicontinuity problem for a supremal functional of the form $F(u,\Omega)=\left
\left
f(x,u,Du)\right
\right
_{L^{\infty}(\Omega)}$ with respect to the strong convergence in $L^{\infty }( \Omega )$, furnishing a comparison with the analogous theory developed by Serrin for integrals. A sort of Mazur's Lemma for gradients of uniformly converging sequences is proved.

Keywords: Supremal functionals, semicontinuity
