Problem Sheet F
- Problems 1 and 2 ask you to do some diagram chasing. Such fun! 🎉
- Problem 3 is another diagram chase. This one is quite hard, but there are pretty colours so that's ok.
- Problems 4 asks you prove the long exact sequence for a triple of spaces (Hint: Use Problem 3!)
- Problem 5 asks you to prove the long exact sequence in reduced homology. (This one is much easier.)
- Problem 5 is about when short exact sequences split.
This is a pretty difficult sheet. 😈
