| Abstract: | We propose precise estimates of the critical index of Gevrey solvability of some classes of linear partial differential equations with multiple characteristics. Sunto Si propongono stime precise dell’indice critico della risolubilità di Gevrey di alcune classi di equazioni lineari differenziali con caratteristiche multiple. To the memory of L. Cattabriga Research partially supported by a Coordinated Research Project of the University of Cagliari and by INDAM-GNAFA, Italy. |
