可积动力系统的环面作用与奇点的自同构群

Torus actions and automorphism groups of singularities of integrable dynamical systems

Nguyen Tien Zung

摘要:

我们证明了在一个实解析可积动力系统(无论是否为哈密顿)的每个"有限型“奇异轨道的邻域中,存在一个保持系统的实解析环面作用,并且该作用在该轨道上是传递的.我们还证明了系统在这样的轨道附近的局部自同构群是

英文摘要:

We show that in the neighborhood of each ``finite type'' singular orbit of a real analytic integrable dynamical system (hamiltonian or not) there is a real analytic torus action which preserves the system and which is transitive on this orbit. We also show that the local automorphism group of the system near such an orbit is
