Hamilton函数发散Birkhoff normal forms的存在性

Existence of divergent Birkhoff normal forms of Hamiltonian functions

Xianghong Gong

摘要:

我们证明了对于$n \geq 2$,存在$\mathbf{R}^{2n}$上的实解析哈密顿系统,其特征值在奇点处为非共振,且Birkhoff规范形本身是发散的.通过分析小因子是如何进入正规形的,给出了结果的证明。

英文摘要:

We show that for $n \geq 2$ there exist real analytic Hamiltonian systems on $\mathbf{R}^{2n}$ with non-resonant eigenvalues at a singular point, of which the Birkhoff normal form itself is divergent. The proof of the result is achieved by analyzing how the small-divisors enter the normal form.
