Canonical edge-colourings of locally finite graphs


A variety of results on edge-colourings are proved, the main one being the following: ifG is a graph without loops or multiple edges and with maximum degree Δ=Δ(G), and if ν is a given integer 1≦ν≦Δ(G), thenG can be given a proper edge-colouring with the coloursc 1, ...,c Δ+1 with the additional property that any edge colouredc μ with μ≧ν is on a vertex which has on it edges coloured with at least ν − 1 ofc 1, ...,c v .
