Title: X-ray spectral features from relativistic accretion discs in AGN

***********************************************************
Abstract: X-ray spectral features from relativistic accretion discs are very important tools to test General Relativity, to study the accretion flows in AGN (and GBH systems) and to estimate the two parameters characterising a Black Hole, namely its mass and angular momentum. I will show how GR and kinematic effects modify the properties of the emission close to the Black Hole, and discuss the observational present status (including recently found evidence f or orbiting spots) and future perspectives.
