Lp-theory for vector potentials and Sobolev's inequalities for vector fields [Théorie Lp pour les potentiels vecteurs et inégalités de Sobolev pour des champs de vecteurs.]
Résumé
In a three-dimensional bounded possibly multiply-connected domain, we prove the existence and uniqueness of vector potentials in Lp-theory, associated with a divergence-free function and satisfying some boundary conditions. We also present some results concerning scalar potentials and weak vector potentials. Furthermore, various Sobolev-type inequalities are given. © 2011 Académie des sciences.
