Learning outcomes
Upon completion of the course, the student possesses basic knowledge of Lagrangian and Hamiltonian mechanics and the main integrable models. In particular, the student is able to write the Lagrangian and Hamiltonian functions of a mechanical system; analyze the phase space for one-dimensional systems; recognize the existence of prime integrals of motion related to symmetries of the system; study the stability of equilibria and solve the equations of motion in the approximation of small oscillations; discuss the solutions of the equations of motion for the central field and the spinning top; use variational principles of least action to write the equations of motion; and use perturbative methods to study mechanical systems.
