  • Abstract A very nice result of Barany and Lehel asserts that every finite subset X or R d can be covered by h ( d ) X-boxes (i.e. each box has two antipodal points in X). As shown by Gyarfas and Palvőlgyi this result would follow from the following conjecture: If a tournament admits a partition of its arc set into k quasi-orders, then its domination number is bounded in terms of k. This question is in turn implied by the Erdős–Sands–Sauer–Woodrow conjecture: If the arcs of a tournament T are… CONTINUE READING
