Syllabus
Prerequisites: Calculus 1, 2, and 3. Physics 1 and 2. Geometry. Analytical Mechanics.
Target skills and knowledge: Relativity: Understanding the foundations of Special Relativity. Ability to solve elementary problems in relativistic mechanics. Ability to use tensor calculus.
Mathematical methods: Basic knowledge of distributions, Fourier transforms, tensor calculus.
Examination methods: Relativity: Written exam with exercises and oral exam with questions about the course topics.
Mathematical methods: Mandatory written exam with exercises and optional oral exam with questions about the course topics.
Assessment criteria: Knowledge and understanding of the course topics, ability in the solution of elementary problems related to the course topics.
Course unit contents: Relativity:
1) Symmetries and invariances. Intertial frames, physical laws, Galilean group. Simultaneity and Newtonian measurements. Speed of light, the aether. Experimental evidences of the finiteness and constance of the speed of light.
2) The new mechanics: the principle of relativity. Postulates of special relativity. Minkowski diagrams. Worldline. Simultaneity. Lorentz transformations.
3) Relativistic kinematics - basics: The interval, the Minkowski metric. Matrix representation of Lorentz transformations. Rapidity. Composition of velocities. Time dilation. Lengths contraction. Penrose-Terrell rotation. The twin paradox.
4) Covariant Relativistic kinematics: Poincaré and Lorentz symmetry groups. Covariant formalism. Tensors. Relativistic momentum. Kinetic energy, rest energy and energy-mass equivalence.
5) Relativistic kinematics - optics: Angle transformations; Stellar aberration. Relativistic Doppler effect.
6) Scattering: Momentum conservation. Particle dacays. Threshold energy. Invariant mass.
7) Electromagnetism: 4-potential and covariant formulation of Maxwell's equations. Gauge invariance. Lorentz transformations of the electromagnetic field. Relativistic invariants. Maxwell equations in vacuo. Solution of the wave equations and its properties. Continuity law for electric currents. Motion of charges in constant electric and magnetic fields.
8) Introduction to General Relativity: The equivalence principle. The metric. Inertial and gravitational forces. Accelerated observers. Rindler spacetime. Time dilation.

Mathematical Methods:
1) Tensors and special relativity: Rotations in euclidean space. Minkowski space, Lorentz and Poincaré transformations. Proper ortochronous transformations. Covariant and contravariant basis. Scalar fields, vector and tensor fields. Divergence and continuity equation in covariant form. Symmetry and Antisymmetry of indices. Differential forms. Exterior derivative. Invariant (Pseudo)tensors: Kronecker delta, metric, Levi-Civita pseudo-tensor. Tensor products and contractions.
2) Distributions: General motivations. Test functions and S(R) space. Regular and singular tempered distributions. Examples: Dirac delta and principal value. Weak convergence. Approximation of singular distributions by means of regular ones. Operations on distributions: derivative, complex conjugation, rescaling and shift of a variable. Dirac delta of a function. Fourier transform and Fourier theorem in S(R). Convolution of functions and their properties. Convolution theorem. Symmetry and reality. Parseval formula. Fourier transform of distributions and Fourier theorem for distributions.
