哈密顿单值性与莫尔斯理论

Hamiltonian monodromy and Morse theory

Nikolay Martynchuk, Henk W. Broer, Konstantinos Efstathiou

摘要:

我们表明,哈密顿单值性的可积的两个自由度的系统与一个整体的循环行动可以计算通过应用莫尔斯理论的系统的哈密顿量。我们的证明是基于Takens的指数定理,它指定了如何能量h陈数的变化时,h通过一个非退化的临界值,并在Fomenko-Zieschang理论的容许周期的选择。我们的结果的连接到一些现有的方法monodromy进行了讨论。

英文摘要:

We show that Hamiltonian monodromy of an integrable two degrees of freedom system with a global circle action can be computed by applying Morse theory to the Hamiltonian of the system. Our proof is based on Takens's index theorem, which specifies how the energy-h Chern number changes when h passes a non-degenerate critical value, and a choice of admissible cycles in Fomenko-Zieschang theory. Connections of our result to some of the existing approaches to monodromy are discussed.
