• Denys Bulavka and Russ Woodroofe, A short proof of the Hilton-Milner Theorem, preprint.
  • arXiv:2411.02513

  We give a short and relatively elementary proof of the Hilton-Milner Theorem.

• Denys Bulavka, Francesca Gandini, and Russ Woodroofe, A Hilton-Milner theorem for exterior algebras, preprint.
  • arXiv:2406.17857

  Recent work of Scott and Wilmer and of Woodroofe extends the Erdős-Ko-Rado theorem from set systems to subspaces of k-forms in an exterior algebra. We prove an extension of the Hilton-Milner theorem to the exterior algebra setting, answering in a strong way a question asked by these authors.
