Let there be given a differential operator on ℝ n of the form D = ∑ i , j = 1 n a i j · x j ∂ / ∂ x i + μ , where A = ( a i j ) is a real matrix and μ is a complex number. We study the following question: To what extent the mapping D : S ' ( ℝ n ) → S ' ( ℝ n ) is surjective? We shall give some conditions on A and μ which assure the surjectivity of D.
