Abstract:
In this paper, we will consider (germs of) holomorphic mappings of the form , defined in a neighborhood of the origin in . Most of our interest is in those mappings where is a germ tangent to the identity and for , and possess no resonances, for these are the so-called Poincaré-Dulac normal forms of the mappings . We construct formal normal forms for these mappings and discuss a condition which tests for the convergence or divergence of the conjugating maps, giving specific examples.
