Symplectic Structures in Physics

In General > s.a. [symplectic structure]; formulations of classical mechanics; higher-order lagrangian theories; Peierls Brackets.
* Idea: In the symplectic formulation of a physical theory, the phase space is given a symplectic structure that makes it a symplectic vector space or manifold ; Then the canonical transformations are those diffeomorphisms that preserve , and they are often generated by the Hamiltonian vector fields of some observables, whose Lie algebra structure coincides with the Poisson bracket structure; In particular, the equations of motion are recovered by giving a function H on and imposing that time evolution be generated by the Hamiltonian vector field of H.
