R\u00e9sum\u00e9<\/strong>: Ce s\u00e9minaire pr\u00e9sente nos travaux sur la stabilit\u00e9 des syst\u00e8mes lin\u00e9aires commut\u00e9s, principalement en dimension deux. Les travaux men\u00e9s avec Ugo Boscain, puis avec Ugo Boscain et Paolo Mason, conduisent \u00e0 une classification compl\u00e8te bas\u00e9e sur les formes normales et la pire trajectoire. En 2009, les conditions de stabilit\u00e9 sont exprim\u00e9es sous une forme de type Hurwitz \u00e0 l\u2019aide d\u2019invariants matriciels. Les travaux avec Daouda Niang Diatta et Aminata Keita unifient ensuite ces crit\u00e8res dans une caract\u00e9risation unique. Enfin, les collaborations avec Philippe Jouan prolongent cette \u00e9tude en dimension sup\u00e9rieure par les ensembles limites et l\u2019observabilit\u00e9.
