    On donne une représentation asymptotique pour \(h\searrow 0\) d'une solution fondamentale du problème de Cauchy associé à l'opérateur pseudo-différentiel \[ - h\partial_t+ H(x, -h \partial_x, t),\quad x\in \mathbb{R}^n\quad t\in \mathbb{R}, \] en utilisant une nouvelle représentation de la distribution de Dirac, conséquence de la formule des polynômes d'Hermite. Les démonstrations seront publiées ailleurs.
