We post here some summaries and some complements to the lecture topics. These notes have been evolved since a few years. They are quite densely written and do not replace the book of course. If you find typos, please email them or talk to me about it. Errata found after the notes being distributed are acknowledged to the right. The files found here are already corrected.
