Soit un difféomorphisme Morse-Smale d’une surface fermée. À une courbe instable de comportement 1 par rapport à un attracteur de correspond une courbe fermée sur un des tores (Bassin. Cette remarque nous permettra de définir de nouveaux invariants de conjugaison de . Nous en déduisons aussi un moyen d’écrire explicitement une puissance de comme le produit du temps 1 d’un champ de vecteurs Morse-Smale topologique par des isotopies à support des disques et des twists de Dehn de supports disjoints.
Let be a Morse-Smale diffeomorphism of a closed surface. The image of an unstable curve of behaviour 1 with respect to an attractor of in (Bassin is a closed curve. This observation allows us to define new conjugation invariants of . It gives also a way of explicitely decomposing a power of as the product of the time 1 of a topological Morse-Smale vector field by isotopies supported in discs and Dehn twists with disjoint supports.
