A Homological Approach to Two Problems on Finite Sets

  title={A Homological Approach to Two Problems on Finite Sets},
  author={Rita Cs{\'a}k{\'a}ny and Jeff Kahn},
We propose a homological approach to two conjectures descended from the Erd ̋ os-Ko-Rado Theorem, one due to Chv ́ atal and the other to Frankl and F ̈ uredi. We apply the method to reprove, and in one case improve, results of these authors related to their conjectures.
