On Gevrey singularities of microhyperbolic operators. (English) Zbl 1293.35375
Summary: We study the Gevrey singularities of solutions of microhyperbolic equations using exponential weighted estimates in the phase space. In particular, we recover some known results on the propagation of Gevrey regularity in an elementary way, using microlocal exponential estimates.
