This sheet is based on Lectures 13 and 14.

  • Problems 1 and 2 are both about verifying the formulas for barycentric subdivision make sense.
  • Problem 3 is just easy.
  • Problems 4-7 ask you to check that three of your favourite theorems from group theory also hold for chain complexes.

This sheet is much simpler than the last one. 😀
