Abstract

For a projective plane ℙn of order n, let κ{script}(ℙn) denote the minimum number k, so that there is a coloring of the points of ℙn in k colors such that no two distinct lines contain precisely the same number of points of each color. Answering a question of A. Rosa, we show that for all sufficiently large n, 5 ≤κ{script}(ℙn) ≤ 8 for every projective plane ℙn of order n.
