This is an invariant of local topological conjugacy. This invariant is a subset of the real numbers, and is either empty or a single point for a diffeomorphism. I would guess that it is not the case in your example. The paper is here (it's written in French) tel.archives-ouvertes.fr/tel-00349243/en | |
