摘要:In this talk, I will introduce a geometric linearization of integrable vector fields around  non-degenerate singularities.I will first recall the classification of singularities of linear systems and  introduce the Poincare-Dulac normal form for nonlinear systems.Then I will present a local normal form of the vector fields formulated by its linear part and its first integrals under the condition of integrability.I will discuss big differences of integrable systems in different categories (formal, analytic, smooth) and give some new results for smooth systems.
