Regularity of infinitesimal automorphisms of involutive structures
Bernhard Lamel, Nicholas Braun Rodrigues
In this paper, we prove that infinitesimal automorphisms of an involutive structure are smooth. For this, we build a regularity theory for sections of vector bundles over an involu…

An FBI characterization for Gevrey vectors on hypo-analytic structures and propagation of Gevrey singularities
Nicholas Braun Rodrigues
In this work we prove an FBI characterization for Gevrey vectors on hypo-analytic structures, and we analyze the main differences of Gevrey regularity and hypo-analyticity concerni…
