Many practical problems encountered in digital signal processing and other quantitative oriented disciplines entail finding a best approximate solution to an overdetermined system of linear equations. Invariably, the least squares error approximate solution (i.e., minimum 2 norm) is chosen for this

Let 0/R N (N 2) be an unbounded domain, and L m be a homogeneous linear elliptic partial differential operator with constant coefficients. In this paper we show, among other things, that rapidly decreasing L 1 -solutions to L m (in 0) approximate all L 1 -solutions to L m (in 0), provided there exis
