Nous donnons plusieurs exemples de familles de formes trace dont l’idéal annulateur dans est principal. Nous montrons aussi qu’en général, cet idéal n’est pas principal.
We give several examples of classes of trace forms for which the ideal of annihilating polynomials is principal. We prove, that in general, the annihilating ideal is not a principal ideal.
