Abstract

Weak continuity for sequences of Jacobians of vector-valued functions in in the sense of Chacon’s Biting Lemma [13] is established via a maximal function method developed by Acerbi and Fusco [1]. A « div-curl » Lemma in the same spirit is also proved. The results are applied to the existence problem of nonlinear elastostatics and to a problem involving rank-one connections appearing in the theory of phase transitions.

Résumé

On démontre un théorème de continuité faible, au sens du lemme de morsure de Chacon, pour des suites de jacobiens de fonctions dans , ainsi qu’un lemme « div-rot ». Pour ce faire, on utilise la méthode de fonction maximale introduite par Acerbi et Fusco.
