We study the formal conjugacy properties of germs of complex analytic diffeomorphisms defined in the neighborhood of the origin of ℂ n . More precisely, we are interested in the nature of formal conjugations along the fixed points set. We prove that there are formally conjugated local diffeomorphisms φ, η such that every formal conjugation [^(s)]hat sigma (i.e. h°[^(s)] = [^(s)] °feta circ hat sigma = hat sigma circ phi) does not extend to the fixed points set Fix(φ) of φ, meaning that it is not transversally formal (or semi-convergent) along Fix(φ).
