Abstract

A labelling of the edges of a graph is called vertex-colouring if the labelled degrees of the vertices yield a proper colouring of the graph. In this paper, we show that such a labelling is possible from the label with numbers of the set for all graphs not containing components with exactly 2 vertices.
