四维C2哈密顿系统的通有动力学

Generic dynamics of 4-dimensional C2 Hamiltonian systems

Mario Bessa, Joao Lopes Dias

摘要:

研究了定义在4维紧致辛流形上的Hamilton流的动力学行为。我们发现存在一个C ~ 2-剩余集的哈密顿量,其中每一个正规的能量表面是Anosov或它是在封闭的能量表面与零李雅普诺夫指数a.e.这是在紧曲面上保面积双同态的Bochi-Mane二分法和其连续时间版本的3维保体积流的精神。

英文摘要:

We study the dynamical behaviour of Hamiltonian flows defined on 4-dimensional compact symplectic manifolds. We find the existence of a C2-residual set of Hamiltonians for which every regular energy surface is either Anosov or it is in the closure of energy surfaces with zero Lyapunov exponents a.e. This is in the spirit of the Bochi-Mane dichotomy for area-preserving diffeomorphisms on compact surfaces and its continuous-time version for 3-dimensional volume-preserving flows.
