Abstract
In [4]L. Hörmander has given sufficient conditions for propagation of C∞singularities for solutions of linear differential operators P with constant coefficients in terms of limit operators called «localization of P at infinity». In this paper a result (Theorem 1.2) of the same type concerning the propagation of Gevrey singularities is given. © 1978 Fondazione Annali di Matematica Pura ed Applicata.File in questo prodotto:
