To the speakers:

Please write carefully notes from your talks. I will scan it and put on this webpage. The notes have to be written carefully with all details. It shoud be basically a verbarim copy of what you will present in class. The notes do not have to be written in TeX. Handwritten notes are OK provided they are legible.
