Sobolev algebra through a " carré du champ " identity
Résumé
We consider abstract Sobolev spaces of Bessel-type associated with an operator. In this work, we pursue the study of algebra properties of such functional spaces through the corresponding semigroup. As a follow-up of [4], we show that under the extra property of a " carré du champ identity " , this algebra property holds in a wider range than previously shown.
