The Fatou coordinate for parabolic Dulac germs
Published 2 Oct 2017 in math.DS | (1710.01268v2)
Abstract: We study the class of parabolic Dulac germs of hyperbolic polycycles. For such germs we give a constructive proof of the existence of a unique Fatou coordinate, admitting an asymptotic expansion in the power-iterated log scale.
