This sheet is based on Lectures 24 and 25.

  • Problems 1-2 fill in gaps from Lecture 24.
  • Problems 3-4 fill in gaps from Lecture 25.
  • Problem 5 asks you to do a computation.
  • Problem 6 is quite hard. Several of you complained that Problem Questions on the Algebraic Topology I exam were harder than those on the Problem Sheets. To rectify this, I'll try and put at least one difficult problem on each Problem Sheet from now on. 😈 This one asks you to give an alternative proof (using homology with coefficients) that an odd map has odd degree (proved last semester in Lecture 15.)

🤓 Feel free to ask a question if you are stuck! 🤓
