| Outline of Final Research Achievements |
Several fundamental results on the strong Gevrey hyperbolicity index have been obtained. In particular, for homogeneous hyperbolic differential operators of order m of which characteristic set is a smooth manifold, the Cauchy problem is Gevrey m/(m-2) well posed for any lower order term if the localization is strictly hyperbolic polynomial on the conormal space and the propagation cone is transverse to the characteristic manifold.
