Title: Intersecting Families of Perfect Matchings

Abstract: A family of perfect matchings of a complete graph is
t-intersecting if any two of its members have t edges in common. It
has been conjectured that such a family cannot have size larger than
(2(n-t)-1)!! for sufficiently large n, and that the extremal families
are precisely those comprised of every perfect matching containing a
fixed set of t disjoint edges. We discuss a proof of this conjecture,
emphasizing the algebraic aspects and techniques surrounding the
proof.
