Dense subsets of \({\mathcal L}^1\)-solutions to linear elliptic partial differential equations
The author gives a geometric condition for an unbounded domain \(\Omega\subset \mathbb{R}^N\) in order that the rapidly decreasing \(L^1\)-solutions of an elliptic homogeneous operator of order \(m\) approximate all \(L^1\)-solutions of this operator.
