Mathematics. Annals of Mathematics. We prove that the Birkhoff normal form of hamiltorlian flows at a nonresonant singular point with given quadratic part is always convergent or generically divergent. The same result is proved for the normalization mapping and any formal first integral. View PDF on arXiv. c# span t performance
