Remarques sur les équations linéaires elliptiques du second ordre sous forme divergence dans les domaines non bornés. (Remarks on linear second order elliptic equations in divergence form on unbounded domains). (French) Zbl 0656.35030
We prove the existence and uniqueness of the solution of the problem \(Au=f\), \(u\in H^ 1_ 0(\Omega)\) in the case that \(\Omega\) is an open unbounded domain in \({\mathbb{R}}^ n\), A is a second order elliptic variational operator with bounded and measurable coefficients and f belongs to \(H^{-1}(\Omega)\).
