Educational objectives
The main aim of this teaching is to provide students with the bases needed to address and solve the most important problems in General Relativity.
Main knowledge acquired will be:
Knowledge of the principles of general relativity.
Knowledge of solutions of Einstein's equations .
Knowledge of the black hole solutions.
Black hole thermodynamics.
Gravitational waves
The main competence ( ie the ability to apply the acquired knowledge ) will be :
Ability to describe the physical consequences of curved spaces.
Knowing how to discuss symmetries and physical properties of solution of Einstein's equations.
Prerequisites
