Propagation of Gevrey singularities for solutions of linear differential operators with constant coefficients (Q5903058)

\textit{L. Hörmander} [Enseign. Math., II. Ser. 17, 99-163 (1971; Zbl 0224.35084)] has given sufficient conditions for propagation of \(C^{\infty}\) 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.
