In this paper we study the lower semicontinuity problem for a supremal functional of the form with respect to the strong convergence in (Ω), 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.
