Subelliptic equations : control, singularities and spectral theory

Equations sous-elliptiques : contrôle, singularités et théorie spectrale Dans cette thèse à la frontière entre analyse et géométrie, nous étudions des équations aux dérivées partielles (EDPs) sous-elliptiques en utilisant des outils récents de géométrie sous-Riemannienne et d'analyse microlocale.
