OVERVIEW
These lectures will give an extended presentation of General Relativity, that is the relativistic theory of gravitation published by Einstein in 1916. Besides the classical applications ot physics (cosmology, gravitational lensing, blackhole), one will stress the mathematical framework required to formulate the theory in a rigourous way (that is, pseudoRiemannian differential geometry), as well as some further mathematical developments inspired by theory.
AIMS AND CONTENT
LEARNING OUTCOMES
In this course we will study some elements of differential geometry useful to rigorously formalize the theory of general relativity. More precisely, the concepts of connection and curvature in pseudo Riemannian spaces will be studied, Einstein's equations and some of their solutions will also be discussed. We will see how mathematics leads to new concepts in physics, such as black holes.
AIMS AND LEARNING OUTCOMES
The course will provide the student with all the mathematical tools necessary to formulate the conceptual basis of general relativity.
More generally, the aim is to show how mathematics and physics harmoniously speak to each other:
 on the one side, we will see why, and how, differential geometry is the right tool to give a rigourous formulation of Einstein's intuition (in particular: the equivalence principle);
 on the other side, we will see how the final formulation of the theory (Einstein equation of general relativity) yields new mathematical developments (like singularity).
PREREQUISITES
Previous knowledge of differential geometry and special relativity will help, but these are not necessary.
All the tools of differential geoemetry needed to the undersatanding of General Relativity will be carefully introduced and explained.
As well, some basics of Special Relativity will be given.

SYLLABUS/CONTENT
0. Scientific and historical introduction to the theory of General Relativity.
1. Fundations of General Relativity
 Special Relativity: Minkowski space, fourvectors, Lorentz group.
 PseudoRiemannian geometry: manifolds, vector fields, connection, tensor, curvature, metric.
 Fundations of General Relativity: trajectories in a curved spacetime, Einstein equations.
2. Solutions and applications
 Linearizzed theory: Newton approximation, gravitational wave.
 Schwarzschild metric: gravitational redshift, precession of the perihelion, bending of the light and gravitational lensing, singularity and black hole.
