The Poisson bracket is a mathematical operator used in classical mechanics, particularly in the context of Hamiltonian mechanics. It provides a way to describe the time evolution of dynamical systems and facilitates the formulation of Hamilton's equations of motion. The Poisson bracket is defined for two functions \\( f \\) and \\( g \\) that depend on the phase space variables (typically positions \\( q_i \\) and momenta \\( p_i \\)).
