For open sets Ω ⊂ R dwe study Hadamard operators on D′ ( Ω ) , that is, continuous linear operators which admit all monomials as eigenvectors. We characterize them as operators of the form L ( S ) = S ★ T where T is a distribution and ⋆ the multiplicative convolution. This extends previous results for the case of Ω = R dbut requires essentially different methods.
