Hamiltonian Systems  

General Types > s.a. classical mechanics; hamiltonian dynamics / phase space; schrödinger equation; statistical mechanics.
* Common forms: The classical ones are of the type H = T + V, with T = \(1\over2\)hij pi pj; > s.a. jacobi dynamics.
* Degenerate: The rank of the symplectic structure is not constant throughout phase space; Phase space is divided into causally disconnected, non-overlapping regions in each of which the rank of the symplectic matrix is constant, and there are no classical orbits connecting two different regions.
* Time-dependent: Cosymplectic structures play a central role in the theory.
* Non-canonical: The equations of motion cannot be obtained from a variational principle, and are of the form

u/∂t = J(u) δ\(\cal H\)/δu .

Specific Types of Systems > s.a. constrained systems; integrable systems; oscillator; parametrized theories; particle physics.
* Coupled oscillators: The Hamiltonian is of the form

H = \(1\over2\)Gab Pa Pb + \(1\over2\)Vab qaqb .

* Single particle: Configuration space = Physical space.
* Lagrangians linear in velocities: Use the Faddeev-Jackiw, or symplectic, method.
@ Quadratic Hamiltonians: Suslov PS(10) [integrals of motion].
@ Other types: Capovilla et al JPA(02)n.SI [curves]; Cariñena et al IJGMP(13) [Lie–Hamilton systems]; > s.a. Continuous Media; projective geometry.

Field Theories > s.a. canonical general relativity; dirac fields; higher-order gravity; klein-gordon fields; membranes; yang-mills gauge theory.
* With boundaries: For each degree of freedom, each piece of boundary gives its conjugate momentum, even a timelike one or a corner!
* Lorentz invariance: There is no simple way to check whether a given Hamiltonian field theory is relativistic or not, and one normally has to either solve for the equations of motion or calculate the Poisson brackets of the Noether charges.
