Nous nous intéressons aux propriétés transverses des feuilletages orientés des surfaces. En particulier, nous donnons des conditions équivalentes à l’existence d’une section globale, en étudiant les formes fermées transverses à l’aide de réseaux ferroviaires.
We prove that for each integer there is an open neighborhood of
the identity map of the 2-sphere , in topology such that: if is a
nilpotent subgroup of with length of nilpotency, generated by
elements in , then the natural -action on has nonempty fixed point
set. Moreover, the -action has at least two fixed points if the action has a finite
nontrivial orbit.
