To be added

Here are some things that should be added to this page:

  • Satellite functors
  • (co)Effaceability and universality of delta-functors
  • dimension shifting
  • examples (application of universality, satellite functors that aren't derived functors, delta-functors that aren't universal, use of dimension shifting)
