Une classe de symboles new-look
Annales de l'Institut Fourier, Tome 30 (1980) no. 3, p. 199-217
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.
