I made plenty of notes during my studies. These are avaible here. All works here are licensed under Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported License . I hope you'll gain benefit from them. Some of them are incomplete, so if you want to use it please revisit later. In case you find any errors, please write me about it! If you can't find what you are searching for I recommend you Csongor Bókay's website. You can find several other notes on his website.
