Nous considérons une certaine classe de groupes de Lie (non-unimodulaires) de type NA de rang un avec des racines non toutes positives, et nous montrons que, sur chacun de ces groupes, il existe un sous-laplacien invariant à gauche particulier qui admet un calcul fonctionnel Lp-différentiable pour tout p∈[1,+∞].
We consider a particular class of (non-unimodular) rank one NA-groups with roots not all positive, and we show that, on each of these groups, there exists a distinguished left invariant sub-Laplacian which admits a Lp-differentiable functional calculus for every p∈[1,+∞].
