I will use these notes on excision in place of Hatcher's exposition on pages 119-124.

We will have the oral exams on Thursday June 4th and Friday June 5th. Please write to rognes@math.uio.no as soon as possible if you are already occupied on one (or both) of these days.

The weekly proposed exercises are listed under Schedule in TP in the List format.  The starred exercises are intended for presentations counting towards the mandatory assignments.

The mandatory assignment for master's students (MAT4530) will consist of presenting solutions to two exercises from Hatcher's book, on Tuesdays starting February 3rd. On week n I will propose exercises for week n+2, marking those that are suitable for this assignment with stars (*). In week n+1 we decide on two students who will give one presentation each, the following week. I can answer questions, as needed. When each student has presented one exercise, we will start over with the second round of exercises.

This replaces the usual written mandatory assignment.  Contact me at rognes@math.uio.no if this arrangement causes difficulties for you.

The lectures will principally cover Chapters 1 and 2 of Hatcher's Algebraic Topology textbook.  More details about each lecture will appear in the "Schedule in TP"; see the List or Teaching formats.
