## Statement

The **Dittert conjecture**, or **Dittert–Hajek conjecture**, is a mathematical hypothesis in [[combinatorics|0JKW7W7XFR]] concerning the maximum achieved by a particular function $\phi$ of matrices with real, nonnegative entries satisfying a summation condition. The conjecture is due to Eric Dittert and (independently) Bruce Hajek.
