This week I finished the ¡­

This week I finished the chapter "Topological classification of compact, closed surfaces". Monday Oct. 23. I will probably use one hour for excercises and then go on to the chapter "Geometry on surfaces -- basic concepts". This is the beginning of the last main topic of the course, which will continue with differential geometry on Tuesday 24. The first installment of the notes for this will be posted by the end of this week.
