Vector potentials in the half-space of $$\mathbb{R}^3$$. (English. Abridged French version) Zbl 0981.35013
Summary: We prove a class of results concerning the vector potentials of divergence-free fields in a half-space of $$\mathbb{R}^3$$. A family of weighted spaces is used as a framework for describing the growth or the decay of functions at infinity.
