The course will be delivered entirely remotely in case of restrictions due to Covid-19. The lectures will be offered in virtual classrooms (zoom platform) in synchronous connection.
Course syllabus
- Lagrange equation: deduction starting from Newton equation, in the case of a point on a smooth surface; deduction in the general case of holonomic constraint. Jacobi energy. The case of keplerian potential: bounded and scattering motions, scattering cross section.
Equilibrium points and normal modes of oscillations.
- Hamilton Equation: deduction of the equation; phase space and Liouville theorem; Poisson brackets and first integrals; canonical transformation. Relation between simmetries and conserved quantities.
- Variational principles: Hamilton principle of least action for both Lagrange and Hamilton equation. Application to the canonical transformation (Lie theorem and generating functions). Principle of Mapertius. Hamilton principle for the vibrating string.
- Relativity: space-time, inertial systems and the the principle of invariant light speed. Deduction of the Lorentz transformations and comparison with Galileo transformations. Some applications: bound on the speed of particles, addition of velocities, Lorentz contraction and time dilation. Geometrical interpretation in space-time: pseudometric and proper time. Twin paradox. Lagrangian of the free particle, momentum, energy and rest energy. Four velocity and four momentum. Relativistic invariance of Maxwell's equations, and the lagrangian of a particle interacting with the electromagnetic field.
