Umeå
Week 6:
Please look carefully at the Preparatory Material page for what you need to review before the course! The lectures will assume that you actually have done the preparations!
Schedule
There is a Campus map at http://www.umu.se/english/about-umu/campus-maps?languageId=1, where you can search for the rooms (e.g. NC352).
