Here is a note about the snake lemma and the long exact sequence in homology associated to a short exact sequence of chain complexes.

Exercise 29 from Section 2.1, and Exercises 2 and 3 from Section 2.2.
I expect that we will have an oral exam, spread over two days, this term. We are looking at June 9.-10., or June (16.-)17. Let me know if any of these dates do not work for you.

I have added a rough plan for the remaining lectures to the course schedule.
Here are my notes for today's lecture on homology.

On Wednesday I finished to computation of the fundamental groups of torus knots – example 1.24 in the book. On Monday I'll do 1.27, 1.28 and 1.29 and then start on section 1.3 "Covering spaces".
Exercises for wed 2/3: Section 1.2: No 1,2, 3, 4, 6, 7, 8, 10, 14.

To day I did 1.1 until "The fundamental group of the circle". I'll continue from there on Monday and basically do all the rest of 1.1 next week. On Wednesday we catch up with the exercises and do exercises 3,4,5 and 6 from 1.1.
Geir
To day I did examples 0.7, 0.8, 0.10 spoke about the homotopy extension property (page 14,15) and proved prop 0.17.
Om monday I'll prove (or at least sketch the proof of) 0.16 and do 0.18. 0.19, 0.20 and 0.21.
And the exercise I postponed.
Exercise for wednesday feb. 3: 18, 19, 21, 22, 24, 25, 27, 28, 29. all from CH 0.

To day I mostly did examples of CW-complexes.
Wedges of spheres, graphs, Spheres, infinite sphere, real projective spaces including the infinite one. I started with complex projective spaces.
On monday I'll continue with complex projective spaces. Do the paragraphs called: operation on spaces, collapsing subspaces and attaching spaces, and may be start on the homotopy extension property.
Exercises:
Ch 0: No 2, 3, 4, 9,10, 11, 14, 15, 16, 18, 19
