bibo_abstract:
- The celebrated Erdős–Ko–Rado theorem about the maximal size of an intersecting
family of r-element subsets of was extended to the setting of exterior algebra
in [5, Theorem 2.3] and in [6, Theorem 1.4]. However, the equality case has not
been settled yet. In this short note, we show that the extension of the Erdős–Ko–Rado
theorem and the characterization of the equality case therein, as well as those
of the Hilton–Milner theorem to the setting of exterior algebra in the simplest
non-trivial case of two-forms follow from a folklore puzzle about possible arrangements
of an intersecting family of lines.@eng
