### Module summary

The Hamiltonian formulation of dynamics is the mathematically most beautiful form of mechanics and (in fact) the stepping stone to quantum mechanics. Hamiltonian systems are conservative dynamical systems with a very interesting algebraic and geometric structure in the guise of the Poisson bracket. Hamilton's equations are invariant under a very wide class of transformation (the canonical transformations), and this leads to a number of powerful solution techniques, developed in the nineteenth century. The subject received a boost in the late twentieth century, with the development of integrable systems, which gave many new examples and techniques, and emphasized the fundamental role of symmetries.### Objectives

1. Derive Lagrangian and Hamiltonian functions and write Hamilton's equations for simple mechanical systems.2. Use symmetries and Noether’s theorem to derive constants of motion.

3. Calculate Poisson brackets and first integrals.

4. Use generating functions for canonical transformations and solve simple cases of the Hamilton-Jacobi equation.

5. Use Lie’s theorem on commuting vector fields and Liouville's Theorem on complete integrability.

**Learning outcomes**

The aim of this module is to develop the theory of Hamiltonian systems, Poisson brackets and canonical transformations. After discussing some general algebraic and geometric properties, emphasis will be on complete integrability, developing a number of techniques for solving Hamilton's equations.
