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…

On a class of globally analytic Hypoelliptic operators with non-negative characteristic form
Nicholas Braun Rodrigues, Gregorio Chinni
The global analytic hypoellipticity is proved for a class of second order partial differential equations with non-negative characteristic form globally defined on the torus. The cl…
