*********************************** * Princeton Discrete Math Seminar * *********************************** Date: Thursday 28th September, 3:00 in Fine Hall 224. Speaker: Ron Aharoni (Technion, Haifa) Title: Rainbow matchings.  Given a family F_1,...,F_m of sets of edges in a graph or hypergraph, a ``rainbow matching'' is a choice of disjoint edges e_1 in F_1,..., e_m in F_m.  The talk is on open problems regarding this notion, some old and some new results, and what topology has to contribute to the subject.
