Variational Principles,The Lagrange equations arising from a Lagrange function are second order differential equations. With this formalism, it is possible to realize constraints (such as occur in applications when objects are affixed to an axle or connected by rods) by simply restricting the Lagrange function.

Symplectic Geometry,When one leaves the special case of linear Hamiltonian differential equations behind, the symplectic bilinear form studied in Chapter . becomes a symplectic form, and Lagrangian subspaces become Lagrangian submanifolds.

Symplectic Topology,In the theory of dynamical systems, topological methods are often employed when the dynamics is too complicated to answer questions like the one about the existence of periodic orbits directly.
