The Dittert conjecture, or Dittert–Hajek conjecture, is a mathematical hypothesis in combinatorics concerning the maximum achieved by a particular function ϕ of matrices with real, nonnegative entries satisfying a summation condition. The conjecture is due to Eric Dittert and (independently) Bruce Hajek. Let A = [ a i j ] be a square matrix of order n with nonnegative entries and with ∑ i = 1 n = n . Its permanent is defined as where the sum extends over all elements σ of the symmetric group. Th
