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, black-hole), one will stress the mathematical framework required to formulate the theory in a rigourous way (that is, pseudo-Riemannian differential geometry), as well as some further mathematical developments inspired by theory.

During these lectures, the various elements of differential geometry needed to formulate General Relativity in a rigourous way will be studied. More precisely, one will introduce the notions of connection and curvature on a pseudo-Riemannian manifold. Then Einstein equations will be discussed, as well as some of their solutions. These include the linearized solutions of gravitational waves, and those with spherical symmetry, used to describe the gravitational attraction of spherical objects.

Besides the learning outcomes described in the general section, some more advanced mathematical topics will be studied as well, such as Hawking-Penrose singularity theorem, or the study of causal structure in pseudo-riemannian geometry.

In presence

0. Scientific and historical introduction to the theory of General Relativity.

1. Fundations of General Relativity

- Special Relativity: Minkowski space, four-vectors, Lorentz group.
- Pseudo-Riemannian geometry: manifolds, vector fields, connection, tensor, curvature, metric.
- Fundations of General Relativity: trajectories in a curved space-time, 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.
- Robertson-Walker metric: cosmology and the Big-Bang.

3. Advanced topics (time permetting)

- Causal structure.
- Singularity.

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.
