Dans un ouvert borné tridimensionnel, éventuellement multiplement connexe, nous prouvons lʼexistence et lʼunicité des potentiels vecteurs en théorie , associés à des champs de vecteurs à divergence nulle et vérifiant plusieurs conditions aux limites. On présente également des résultats concernant les potentiels scalaires et les potentiels vecteurs faibles. De plus, plusieurs inégalités de Sobolev sont données.
In a three-dimensional bounded possibly multiply-connected domain, we prove the existence and uniqueness of vector potentials in -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.
