Abstract

A weightingwof the edges of a graphGinduces a colouring of the vertices ofGwhere the colour of vertexv, denotedc<subscript>v</subscript>, is$$ {\sum\nolimits_{e \mathrel\backepsilon v} {w{\left( e \right)}} } $$. We show that the edges of every graph that does not contain a component isomorphic toK<subscript>2</subscript>can be weighted from the set {1, . . . ,30} such that in the resulting vertex-colouring ofG, for every edge (u,v) ofG,c<subscript>u</subscript>?c<subscript>v</subscript>.
