Hamiltonian mechanics - Wikipedia
In physics, Hamiltonian mechanics is a reformulation of Lagrangian mechanics that emerged in 1833. Introduced by Sir William Rowan Hamilton, [1] Hamiltonian mechanics replaces …

这篇笔记整理最优化问题求解中的汉密尔顿方程（Hamilton Equation），之前导论提到，共有变分法、最优控制、和动态规划三种方法可以解决动态最优化问题。
14.3: Hamilton's Equations of Motion - Physics LibreTexts
Now the kinetic energy of a system is given by \( T=\dfrac{1}{2}\sum_{i}p_{i}\dot{q_{i}}\) (for example, \( \dfrac{1}{2}m\nu\nu\)), and the hamiltonian (Equation \( \ref{14.3.6}\)) is defined as …
【知识仓库】哈密顿力学-哈密顿方程 - 知乎 - 知乎专栏
这部分我们将讨论关于哈密顿方程 (Hamilton's Equations) 的内容，其实应该叫哈密顿方程组更合适。 回顾一下哈密顿量的表达 H = \sum_k \dot{q}_k \frac{\partial \mathcal{L}}{\partial …

哈密顿力学的目标是用广义动量（也称为共轭动量）变量取代广义速度。 这样一来，就可能处理特定的系统，例如量子力学的某些方面，否则其表述会更复杂。 在 直角坐标系 中，广义动量就 …
Hamiltonian description is a stepping stone to other areas of modern physics: phase space and Liouville’s theorem are useful in statistical mechanics, Poisson brack-ets and time-translation …
the Hamiltonian is now most familiar as the operator in quantum mechanics which determines the evolution in time of the wave function. We begin by deriving Lagrange’s equation as a simple …
where, in the end, we’ve eliminated r˙ in favour of p and written the Hamiltonian as a function of p and r. Hamilton’s equations are simply r˙ = @H @p = 1 m p p˙ = @H @r = rV (4.20) which are …
