Canille Martins, Julio Cesar [UNESP]2022-04-282022-04-281992-01-01Transactions of the American Mathematical Society, v. 329, n. 2, p. 825-837, 1992.0002-9947http://hdl.handle.net/11449/223892The topological classification, by conjugacy, of the germs of holomorphic diffeomorphisms f: C2, 0 →C2, 0 with df(0) = diag(λ1, λ2), where λ1 is a root of unity and | λ2 | ≠ 1 is given. This type of diffeomorphism appears as holonomies of singular foliations Fx induced by holomorphic vector fields X: C3, 0 → C3, 0 normally hyperbolic and resonant. An explicit example of a such vector field without holomorphic invariant center manifold is presented. We prove that there are no obstructions in the holonomies for Fx to be topologically equivalent to a product type foliation. © 1992 American Mathematical Society.825-837engArtigo10.1090/S0002-9947-1992-1073776-02-s2.0-0012269754
