Each nonzero solution of the stationary Schrodinger equation Deltau(x) - c(r)u(x) = 0 in R-n with a nonnegative radial potential c(r) must have certain minimal growth at infinity. If r(2)c(r) = O(1), r --> infinity, then a solution having power growth at infinity, is a generalized harmonic polynomial. [References: 15]
