Presents equations of motion attached to linear Hamiltonians in generators of the real Jacobi group G^J_n(R) on the extended Siegel-Jacobi upper half space using its energy function.
A review presents the geometry of pre-symplectic and pre-contact manifolds and develops constraint algorithms for admissible phase space in Hamiltonian systems with degeneracies.
