On the heterochromatic number of hypergraphs associated to geometric graphs and to matroids

Juan José Montellano-Ballesteros, Eduardo Rivera-Campo

The heterochromatic number hc(H) of a non-empty hypergraph H is the smallest integer k such that for every colouring of the vertices of H with exactly k colours, there is a hypered…
