Department of Mathematics, University of sciences and technology, Oran, Algeria; Department of Mathematics, University Ibn Khaldoun, Tiaret, Algeria

Abstract: Considering a class of differential operators with constant coefficients including the hypoelliptic operators, we show that the comparison of the operators implies the inclusion between their spaces of Roumieu vectors.

Keywords: iterates of operators; Roumieu spaces; comparison of operators

Classification (MSC2000): 35B65; 35H10
