When does a Lagrangian dynamical system have an equivalent Hamiltonian description?
Here's what I have done:
$\bullet$ Let the Lagrangian $L(q_{i},\dot{q}_{i},t)$, which under the point transformations
$$
\{q_{i}\}\leftrightsquigarrow\{Q_{i}\}
$$
given by the invertible relations $ …

Practical example of Hamiltonian reduction
If i correctly understand your question, i think what you are talking about is the so called Poincare reduction method. This actually generalises Liouville integrability, in the sense that in the pres …
