Dans un domaine simplement connexe Ω de R3, le noyau de l'opérateur CURLCURL agissant sur des champs de matrices symétriques de Ls2(Ω) dans Hs−2(Ω), coïncide avec l'espace des champs de tenseurs de déformation linéarisés. Dans le cas de domaines non simplement connexes, Volterra a caractérisé ce noyau pour des champs réguliers. Dans cette Note, nous étendons ce résultat pour un domaine à frontière lipschitzienne et pour des champs dans Ls2(Ω).

In a simply-connected domain Ω in R3, the kernel of the operator CURLCURL acting on symmetric matrix fields from Ls2(Ω) to Hs−2(Ω) coincides with the space of linearized strain tensor fields. For not simply-connected domains, Volterra has characterized this kernel for smooth fields. Here we extend this result for domains with a Lipschitz-continuous boundary for fields in Ls2(Ω).
