In addition to the notes on stability that I've already posted, I have a set on Composites, which also originated from a lecture course that I gave in Ecole Polytechnique, around 2002. In the hope that they may be of interest at least to someone, here they are! Please do remember that they are just notes and may not be error-free.

I wrote these notes about 10 years ago to supplement a course of lectures at Ecole Polytechnique.  There might be errors in the notes, but I hope they can help you learn this fascinating subject of lasting value.
