Discrete-time generalized canonical transformations for non-autonomous systems
Leonardo Colombo, David Martin de Diego, Riccardo Muradore +2
The paper introduces a geometric discretization method for time‑dependent Hamiltonian systems that uses generalized canonical transformations to create structure‑preserving integra…

From Euler-Jacobi to Bogoyavlensky and back
Davide Murari, Nicola Sansonetto
This work focuses on two notions of non-Hamiltonian integrable systems: B-integrability and Euler-Jacobi integrability. We first show that the first notion is stronger. We then inv…
