Degenerate characteristic directions for maps tangent to the identity. (English) Zbl 1280.37041
Summary: Let \(F:(\mathbb{C}^2,O)\to(\mathbb{C}^2,O)\) be a holomorphic germ tangent to the identity. Assume \(F\) has a characteristic direction \([v]\). In [Duke Math. J. 92, No. 2, 403–428 (1998; Zbl 0952.32012)], M. Hakim gives conditions to guarantee the existence of an attracting basin to the origin along \([v]\), in the case of \([v]\) a non-degenerate characteristic direction. In this paper, we give conditions to guarantee the existence of basins along \([v]\) in the case of \([v]\) a degenerate characteristic direction.
