A unique-maximum k-edge-colouring with respect to faces of a 2-edge-connected plane graph G is an edge-colouring with colours 1,…,k so that, for each face α of G, the maximum colour occurs exactly once on the edges of α. We prove that any 2-edge-connected plane graph has such a colouring with 3 colours. If we require the colouring to be facially proper then 6 colours are enough. |
