On Hamiltonian systems integrable in elliptic functions that describe waves over underwater banks and ridges
Yu. Brezhnev, A. Tsvetkova
We discuss the 4-dimensional Hamiltonian systems that describe waves over underwater banks and ridges. The systems are exactly integrable in terms of elliptic functions and of solu…
