本文为部分可积哈密顿系统引入作用量积分,在遍历性假设下证明其成为平均动力学的运动常数,并进而成为绝热不变量。

中文摘要 AI 辅助

我们为部分可积哈密顿系统引入了作用量积分,这些积分在非可积理论与完全可积理论之间进行插值。我们证明,在哈密顿系统在其积分公共水平集上具有遍历性的假设下,这些作用量成为平均动力学中的运动常数,并因此当哈密顿函数允许随时间缓慢变化时,成为绝热不变量。

英文摘要

We introduce action integrals for partially integrable Hamiltonian systems that interpolate between the non-integrable and completely integrable theory. We show that under the assumption of ergodicity of the Hamiltonian system on the common level sets of its integrals, these actions become constants of motion for the averaged dynamics and, consequently, adiabatic invariants when the Hamiltonian function is allowed to slowly change with time.
