Hello, This list is intended to discuss the content of the lectures. Preferably in english since one of us (Chaim Goodmann Strauss) is english speaker. Below is a link on a wiki intended to build a summary of the lectures. Please check that "your" lecture is the one you though. You are assumed to fill by yourself its content (in a sketchy way - this is to avoid redundancy and to know what students could be assumed to have learn in previous lectures). To help you (and maybe force you to react) I've already filled some point of your lectures :) You can of course modify it, as well as you can add something to some other lecture, meaning that you would like that the lecturer speaks about this in his lecture. To edit the wiki, click the link "edit" on the bottom-left of the webpage. The login is "qc" (for "quasicool") and the password "cq" is obtained by a flip. Finally, the promised link on the wiki: https://lipn.univ-paris13.fr/~fernique/quasicool/index.php?n=Site.TilingsAnd... So, please edit, and do not be afraid of making errors, one can get things back. I would like to achieve this before 2015. There is 3 or 4 items to add, is seems possible! bests, Thomas
