Week 48

Thursday Nov.27 was the last regular lecture, and I finished the proof of the Gauss-Bonnet theorem. Week 49 (Tuesday Dec.2. and Thursday Dec.4) will be devoted to problem-solving, starting with problems 4-9 from Chapter 5.9.  After that I will discuss  some problems from old exams, starting with the final exam 2013.  Note also that you can find suggested solutions to most previous exams on the web pages from the corresponding semesters.
