Nambu mechanics

Nambu mechanics is a theoretical framework in classical mechanics that generalizes the standard Hamiltonian and Lagrangian methods. It was developed by Yasunori Nambu in the 1970s as a way to describe systems with constraints and to deal with more complex types of motion. In Nambu mechanics, the equations of motion are formulated using a Nambu bracket, which is an extension of the Poisson bracket used in Hamiltonian mechanics.
