摘要
We show several results providing global fixed points for nilpotent groups of orientation-preserving C-1 diffeomorphisms of the plane R-2. The main cases are namely groups of diffeomorphisms of the sphere such that infinity is a global fixed point, groups of diffeomorphisms preserving a non-empty compact set and finally groups of diffeomorphisms preserving a probability measure.
