On construit par voie géométrique une classe de symboles classiques en dehors d’une sous-variété. La classe d’opérateurs pseudodifférentiels associée contient les paramétrix d’opérateurs tels que ∑ i=1 n-1 ∂ ∂x i 4 +∂ ∂x n 3 ou ∂ ∂x n 3 +∑ i=1 n-1 ∂ ∂x i 2 .

We construct, in a geometric way, a class of symbols which are classical except along some submanifold. The parametrics of ∑ i=1 n-1 ∂ ∂x i 4 +∂ ∂x n 3 and ∂ ∂x n 3 +∑ i=1 n-1 ∂ ∂x i 2 , for instance, belong to the associated class of pseudodifferential operators.
