An FBI characterization for Gevrey vectors on hypo-analytic structures and propagation of Gevrey singularities

Abstract

In this work we prove a FBI characterization for Gevrey vectors on hypo-analytic structures, and we analyze the main differences of Gevrey regularity and hypo-analyticity concerning the FBI transform. We end with an application of this characterization on a propagation of Gevrey singularities result, for solutions of the non-homogeneous system associated with the hypo-analytic structure, for analytic structures of tube type.Date: March 2020. 1 In the context of hypo-analytic structures, by analytic regularity we mean hypo-analyticity
