*********************************** * Princeton Discrete Math Seminar * *********************************** Date: Thursday 23rd October, 3:00 in Fine Hall 224. Speaker: Eli Berger (U. Haifa) Stein's conjecture and other fair representation problems Stein's conjecture states that if an n x n matrix has entries 1...n, where each symbol appears exactly n times, then there exists a generalized diagonal where all but two symbols appear exactly once. I will talk about this conjecture and other settings in which we look for a small structure proportionally representing the bigger structure from which it is taken.  ----------- Next week: fall break. Week after: TBA. Anyone wishing to be added to or removed from this mailing list should contact Paul Seymour (pds@math.princeton.edu)
